\nBritish Bangladeshis are citizens or residents of the United Kingdom whose ancestral roots are from Bangladesh. Bengali Muslims have prominently been migrating to the UK since World War II. Migration reached its peak during the 1970s, with most originating from the Sylhet Division. The largest concentration live in east London boroughs, such as Tower Hamlets. This large diaspora in London leads people in Sylhet to refer to British Bangladeshis as Londonis.
