The largest Bengali-speaking community in Britain is in London. Roughly half of London's Bengalis live in the riverside borough of Tower Hamlets, though there are large communities in Camden and Newham.
In Tower Hamlets the Bangladeshi community is almost a third of the total population. This community was the last to arrive in London by sea. All subsequent migrants arrived by air and many of them settled in west or north London, nearer Heathrow Airport. The arrival of the Bengali community coincides with the final decline of the port of London for passenger services.
