British Sri Lankan Tamil
British Sri Lankan Tamil (பிரித்தானியத் இலங்கை தமிழர்) refers to a demographic construct concerning British citizens and residents who descend from Tamils on the island of Sri Lanka. It's notable that the definition frequently excludes those on the island that have been segregated into other groups, namely Sri Lankan Moors (Muslims) and Hill Tamils. 
The United Kingdom is home to the largest population of Sri Lankan Tamils in Europe, albeit only by a narrow margin, and it is among the most populous communities of Sri Lankan Tamils worldwide. An estimate by the Financial Times placed the number of Sri Lankan Tamils in the UK at just under 200,000.
Sri Lankan Tamils can be part of several other larger demographic groups and therefore many Tamils will not identify as "Sri Lankan Tamil". These include: British Tamil, British Sri Lankan, British Indian, and British Asian. There are fluid connections between British Sri Lankans and British Indians, particularly along ethnolingustic and ethnoreligious lines.
Sri Somasundaram Sabapathipillai was a famous early immigrant to the UK. A lawyer born in 1910, he founded the Hindu Association of Great Britain in 1966, which in turn established the first Hindu temple in Europe in 1981 - servicing the needs of the Tamil community.

The upheaval caused by the Civil War caused many people to uproot from the island and move to more peaceful countries, a consequence being that a significant number of Tamils from the island immigrated to the United Kingdom; the majority of these immigrants settled using student visas and family reunion visas.
A few immigrants established a handful of community networks, such as Tamil Pages, in order to service the needs of Tamils, with a large number of activist political organizations being created in order to advance political viewpoints concerning the Civil War - mainly of Tamils on the island.
The immigrants managed to settle in the UK using student visas and educated themselves into higher ranking jobs - they are viewed as an example of successful integration - and they have a more middle class profile.
A large business profile has been founded in the UK, with the Tamil Chamber of Commerce stating that Tamil businesses generate around $1 billion for the UK economy; two global telecommunication companies have been founded by immigrants - including Lebara and Lyca.
There have been many activist political movements held by some immigrants in relation to the Civil War and the most notable demonstration was held in April 2009 in London where around 100,000 people attended. 
A significant population of second generation exist in the UK. They are typically brought up away from other people of their own ethnicity, and without siblings due to sub-replacement fertility rates in the community, with their parents working their way into higher-ranking professional jobs by utilising educational facilities.
The youngest person to pass their A-Levels in the UK is "Ganesh Sittampalam", and this is symbolic of the progressive rates of social mobility and educational attainment professed by the second generation.
The majority of these people have entered higher education and found themselves in jobs sectors such as the financial and medical industry - most notably mirroring people descended from the Republic of India.
The UK has always had a strong, albeit small, population of Sri Lankan Tamils deriving from colonial era immigration between Sri Lanka and the UK, but a surge in emigration from Sri Lanka took place after 1983, as the civil war caused living conditions deteriorate and placed many inhabitants in danger. It is now estimated that the current population of British Sri Lankan Tamils numbers around 100,000 to 200,000.
They are spread out throughout the country, in a manner similar to other Hindus, and did not segregate in the manner that Muslims and Blacks have, an abnormal circumstance being found in the London borough of Kingston, where around 6% (~10,000) of the population is of Sri Lankan and/or Tamil origin.
The largest population of British Sri Lankan Tamils can be found in London, chiefly in Harrow (West London), where a large Hindu Indian population has existed for decades, and Tooting (South London). The community generally has far lower birth rates in comparison to other South Asian ethnic groups, with one child for two parents being the norm.
Unlike immigrants to countries in Continental Europe, the majority of Sri Lankan Tamils that went to live in Anglo-Saxon countries achieved entry through non-refugee methods such as educational visas and family reunion visas, owing to the highly educated in Sri Lanka being literate in English as well as Tamil. This resulted in the first generation diaspora falling into highly professional jobs such as medicine and law after studying at British educational facilities.
The result was that the community was perceived as being similar to the rest of the Hindu Indian community (see:Ugandan Indian Refugees) and therefore also gave them a more middle class image.  They are viewed as an example of successful integration as the community did not suffer from the problems with criminality, anti-social behaviour, or poor socioeconomic demographics that have plagued other communities such as Muslims.
The Tamil Chamber of Commerce (TCC), for example, estimated in March 2011 that there are five thousand Tamil-owned businesses in UK with a turnover of 1 billion GBP.

The Sri Lankan Civil War has played a crucial role in the political actions of the Sri Lankan Tamil community. A number of activist organisations have been established by first generation immigrants in order to represent the voice of the Sri Lankan Tamils on the island, and several major protests have been held in order to forward various viewpoints about the Civil War, most notable of which was a mass demonstration in April 2009 which drew nearly 100,000 protestors.
The second generation have however generally been more emotionally detached from the politics of the civil war, giving more priority to the issues in the United Kingdom and European Union, and preferring to refrain from involving themselves into the more extreme activism surrounding the Civil War. A number of political persons, such as Chamali Fernando, have advocated harder stances against asylum seekers and terrorism.
The second generation generally do not speak Tamil fluently enough to relate to South Asian culture and media, beyond news and politics, and therefore have traditionally avoided popular Indian culture like Kollywood (music and films) and literature. A number of scholars have suggest that this points to a relative success of integration by the community.
The second generation have received little targeted attention from scholars, but some information has been collected as part of academic surveys of the general population; The Economist noted how westernisation had affected second generation minorities in the UK, noting that they "having abandoned their parents’ native language, food and clothing" tended to rally around the Muslim identity.
The community, while in theory should be more liberal than other communities in Western and Southern Asia, has some paternal aspects that clash with liberal western youth values. A number of second generation have commented on how their first generation parents tend to look down on many elements of western youth culture (binge drinking, illegal drugs, promiscuity, etc.), and issues such as mental illness, homophobia, colourism, and misogyny have often received minor vocal opposition from first generation Sri Lankans.
However, there are elements of Sri Lankan Tamil culture that are markedly more liberal than other South Asian communities. There is widespread tolerance towards the concept of love before marriage and the majority of Tamils are not subject to forced marriage (arranged marriages are always optional), and women are often encouraged to participate in the education and labour market prior to marriage.
Sri Lankan Tamils are predominantly Hindu, albeit a large Christian population exists; much of Sri Lankan Tamil traditional culture is rooted in Hinduism and Christian Tamils find it increasingly difficult to maintain a cultural identity that is separate and distinct from Hinduism. 'Raj' argued that there has been a 'Hindu resurgence' in the UK, whereby the young second generation living in the Hindu diaspora are reconstructing and realigning themselves with the faith of their parents.
Chakravoty discusses how British Sri Lankan Tamil youth often carried forward elements of religion from their parents into their own daily lives, such as the widespread practice of religious rituals such as the Bharatnatyam.
London is today home to at least 23 Saivite temples founded by Sri Lankans, and the Hindu Association of Great Britain was founded by them in 1966 to foster relations among Hindus.The latter organisation established Europe's first Hindu temple, the Wimbledon Ghanapathy Temple, in the 1980s.
