Solomon Ridgeway Dias Bandaranaike, the fourth prime minister of Ceylon (now Sri Lanka), spent six years in England. He studied between 1919 and 1925 at Christ Church College, Oxford. During his time there, he lived with a working class family as a shortage of rooms in the College had forced Christ Church to find lodgings elsewhere. Bandaranaike was struck by the hierarchical structure and social conventions that excluded him from the student fraternity.

During his first year at Oxford, his father moved to London for a year together with his sister who was presented as a debutante at Buckingham Palace in 1920. Bandaranaike tried hard to fit in and found it difficult to deal with his fellow students’ rejection, especially considering his own family’s preoccupation with status and power. In 1920 he was allotted a room in Christ Church College, sharing a corridor with Anthony Eden. After passing his classics exams with a second class degree, he switched to law.

In his third year at Oxford he became actively involved in the Oxford Union, delivering speeches on democracy, policies on India, and the British government’s policies in Egypt. He established himself as a regular speaker at the Union and his performance was praised in the Oxford Magazine for its ‘vigorous thinking and his animated, insistent delivery’ (4 May 1922) . In June 1923, he became Secretary of the Oxford Union and in March 1924 was elected Junior Treasurer. His exposure to Indian Nationalism at Oxford had a profound impact on his world view. It led him to conclude that his father’s political support for the British and the feudal system in Ceylon were anachronistic.

Bandaranaike returned to Ceylon in 1925 and became actively involved in the island’s politics and independence movement. He was elected to the Colombo Municipal Council in 1926 and joined the United National Party. He was a member of the State Legislature from 1931 onwards. He became Ceylon’s fourth prime minister in 1956 and was assassinated in 1959.

Ananda Kentish Coomaraswamy was the son of Sir Mutu Coomaraswamy, from Ceylon, and his wife Elizabeth Clay Beeby, from Kent. Coomaraswamy joined Wycliffe College in Gloucestershire in 1889 and then studied Botany at University College London, graduating in 1900. He married Ethel Mary Partridge in 1902 and worked for the Minerological Survey in Ceylon, 1903-6.

In 1910, Coomaraswamy was involved in the formation of the India Society in London - a society dedicated to promoting Indian art. He wrote a number of pamphlets on Indian art and in 1917 took up a position as Research Fellow in Indian, Persian and Muhammadan Art at the Boston Museum of Fine Arts.

In 1912, he divorced his first wife. His second wife was Alice Richardson, a performer of Indian music. His third wife was the American artist Stella Bloch, but this marriage was short-lived.

S. A. Wickremasinghe was born in Akurassa, Ceylon, now Sri Lanka, in 1901. He was schooled in Ananda College, Colombo. He first arrived in Britain for his education in 1926. In 1927 he was joint secretary of the Indian Majlis student society and had active links to the Communist Party of Great Britain. In 1929 he graduated with an MBBS from the University of London where he also got his MRCP form the Royal College of Physicians.

By 1931 he had returned to Ceylon and with Philip Goonewardena was involved in social work, helping lower caste communities. Wickremasinghe was a member of Ceylon's State Council from 1931-6, advocating complete independence. He lost his seat in the 1936 election.

He subsequently returned to London with his wife, Doreen Young, to open a doctor's surgery in South London, near Elephant and Castle. During his time in London he became involved in the India League and renewed his links with the Communist Party of Great Britain. Wickremasinghe was a founding member of the Lanka Sama Samaja Party in 1938, which convened regular meetings and protests, often in conjunction with the India League in London. He co-organized with Krishna Menon a conference on 'Socialism in India and Ceylon' in 1938. Wickremasinghe and the Sama Samaja Party were closely associated with Ben Bradley and the Communist Party of Great Britain. He founded the Communist Party of Ceylon in 1943. In 1945 he represented Ceylon at the inaugural World Labour Organisation held in France. He continued to campaign for Ceylon's independence and remained involved with leftist politics in Sri Lanka until his death in 1981.

Of an elite Parsee background, Avabai Wadia arrived in Britain aged 14, accompanied by her mother and to join her brother. She attended Brondesbury and Kilburn High School in London where she was the only South Asian pupil. She excelled at school and went on to train as a barrister at Lincoln’s Inn, becoming the first Ceylonese woman to pass the Bar exams. As a direct consequence of her success, the Law College in Colombo opened its doors to women. She was called to the Bar in 1934 and eventually found a chambers willing to take on a South Asian woman. Committed to women’s rights, Wadia was an active member of a number of women’s organizations in Britain. She was also involved with the Labour Party and the Indian nationalist movement in Britain. On her return to India, she pioneered the family planning movement.

Kamal Athon Chunchie was a Methodist minister and the founder of ‘The Coloured Men’s Institute’ in Tidal Basin Road, Victoria Docks, Canning Town. He was the eldest of nine children born in Ceylon (now Sri Lanka) to Muslim parents of Malay origin. His father was one of the leading Muslim figures in Ceylon. He was educated at Kingswood College, Kandy. In 1915 he enlisted in the public schools battalion, 3rd Middlesex regiment, joining around 28,500 other South Asian troops in the trenches. During the First World War, he saw active service on the Western Front, in Italy and Salonika. Chunchie converted to Christianity while convalescing in an Army hospital in Malta. He arrived in London on 6 March 1918. Towards the end of the war, while stationed in Chatham, he met Mable Tappen, who was stationed there as a member of the Women’s Army Auxiliary Corps. They married in July 1920 and had one daughter, Muriel.

In December 1921, Chunchie began to work as a missionary for the Wesleyan Methodist Missionary Society among the Asian, Chinese, African and Caribbean sailor community in the Canning Town area of London. He initially took up a position at the Queen Victoria Seamen's Rest in Poplar, which was affiliated with the Wesleyan Methodist Missionary Society. He would visit the local residents and the seamen population in ships, hospitals, and lodging-houses, preaching to them and providing material assistance. His missionary and philanthropic work also extended to the small ethnic minority community resident in the docklands, many married to white partners, and their children, as well as colonial and Indian students. Chunchie spoke out against racism and the plight of the dispossessed in the East End which he saw as incompatible with Britain's Christian values.

In 1923, in a rented hall in Swanscombe Street, Chunchie founded the Docklands' first black Wesleyan Methodist church, and a Sunday school. In his efforts to counter racist discrimination of the black and Asian population he lobbied for the establishment of an organization that catered for London’s East End’s black and Asian community, a plan that came to fruition in 1926 with the establishment of the Coloured Men’s Insitute (CMI) in Tidal Basin Road, Canning Town. It was a religious, social and welfare centre for sailors and local residents with Chunchie as the responsible pastor and warden. From 1926 until the centre's demolition as part of the West Ham Road widening scheme in 1930, Chunchie worked tirelessly as a fund-raiser to keep the centre open, addressing Methodist gatherings all over the UK. He was an accomplished speaker, invoking the Christian ideals of equality and brotherhood to combat racism, unmasking the hypocrisy of Christian England and its attitudes to race. Chunchie was well-respected and well-liked by the black community in East London; however he faced criticism from the East End Branch of the Universal Negro Improvement Association, who accused Chunchie of patronizing black people and fostering segregation. Chunchie was also criticized by the Methodist Mission House over his management of the CMI. After 1930, no plans were drawn up to reopen the CMI elsewhere and Chunchie worked as a missionary deputation in the home church from 1930 to 1932.

Chunchie, however, would continue to work tirelessly to relaunch the CMI as an independent organization. With the support of a multi-racial council that included Dr Harold Moody of the League of Coloured Peoples, Professor R. K. Sorabji, and Lady Lydia Anderson and dedicated volunteers, amongst them his wife, he worked hard to build a new CMI. However, due to a lack of funding this never came to fruition, which meant that Chunchie had to use the limited facilities of the Presbyterian church in Victoria Dock Road as the centre and his own home as a base to continue the numerous pastoral, charitable and religious activities of the CMI.

Chunchie played cricket for Essex, was a member of the Royal Empire Society (from 1935), and was vice-president of the League of Coloured Peoples (1935–7). During the Second World War he was a member of the voluntary firefighting party in Lewisham, South London. In 1943 he also attended meetings of Swaraj House. He died on 28 June 1953 after a heart attack. He is buried in Hither Green cemetery.

Merle Oberon was born in India to a Welsh father, Arthur Thompson, who worked in Bombay as a railway engineer and his Ceylonese wife Constance. She was educated in India until the age of 17, when she left for London, where she worked as a hostess in the Café de Paris and as an extra in British films. In the early 1930s, she was discovered by the film producer Alexander Korda, whom she later married (they divorced in 1945), who cast her as Anne Boleyn in his 1933 film The Private Life of Henry VIII and created her screen name Merle Oberon for her. Her most critically acclaimed performance was in the 1939 film adaptation of Wuthering Heights as Cathy, starring alongside Laurence Olivier’s Heathcliff.

Oberon had a complex relationship with her dual heritage, especially after her move to Hollywood. On her arrival in England in 1927, she would call herself ‘Tasmanian’, thinking that her mixed-race heritage and her Indian origin might be an obstacle to her career. In company she would introduce her mother, who for many years accompanied her, as her maid.

Oberon worked with prestigious directors such as Korda, Ernst Lubitsch, René Clair, Jules Duvivier, King Vidor, and William Wylerand starred alongside some of Hollywood’s most famous male stars, Gary Cooper, Charles Laughton, Douglas Fairbanks senior, Leslie Howard, Laurence Olivier, George Sanders, and Marlon Brando among them.

Oberon died of a stroke in Los Angeles on 23 November 1979.

Alagu Subramaniam was a Ceylon-born English short story writer. He was one of the founders and editors of the literary magazine Indian Writing. Mulk Raj Anand and Iqbal Singh also published one of his short stories in their anthology Indian Short Stories (New India Publishing Company, 1946). His short stories were published by a number of journals, such as Life and Letters Today and the Left Review. He was also involved with the anti-colonial organization Swaraj House.

A Sri Lankan Tamil from an affluent English-speaking Roman Catholic family, M. J. Tambimuttu arrived in Britain at the age of 22. Having already published three volumes of poetry in Ceylon, he soon immersed himself in the literary world of London’s Soho and Fitzrovia. Within little more than a year of his arrival he had founded the magazine Poetry London (1939–51) with the writer and musician Anthony Dickins. While Dickins' involvement quickly diminished, Tambimuttu edited the first fourteen volumes of the magazine and a number of books, as well as writing his own poetry. In July 1943, with the backing of publishers Nicholson and Watson (on the recommendation of T. S. Eliot who was an admirer of his), he established Editions Poetry London, which published contemporary verse and prose, as well as art books, in hard cover. Tambimuttu was also a regular participant in the BBC radio series Talking to India during the Second World War. A man of charisma as well as a talented editor, he had an array of friends and acquaintances with whom he enjoyed the pubs and cafes of Fitzrovia.

Tambimuttu returned to Sri Lanka in 1949 then moved to New York in 1952 where he launched the magazine Poetry London–New York (1956–60) as well as continuing to publish short fiction and poetry of his own, and lecturing at the Poetry Center and New York University. In 1968 he returned to London where he founded a final magazine, Poetry London/Apple Magazine, which had just two issues, and a publishing company, the Lyrebird Press. He died of heart failure in London in 1983.
