The enlargement of the EU in 2004 gave a number of countries in the former Eastern Bloc freedom of movement across Europe, including to the UK. 3 countries that had been part of the Soviet Union were now in the EU – the Baltic states of Estonia, Latvia and Lithuania.
It was the Lithuanians who most readily made London their home. There are 40,000 Lithuanian born Londoners, compared to around 10,000 Latvians and fewer than 3,000 Estonians.
Lithuanians are strongly concentrated in East London, especially Newham where there are more than 8,000. Waltham Forest, Redbridge and Barking and Dagenham also have significant populations.
