Fullfact, the UK's independent fact checking charity, in their 'Brits Abroad' report estimated that 5.5 million British people live permanently abroad – almost one in 10 of the UK population.
They estimate that 1.24 million Brits live in the EU which is broken down as follows:
Spain had the most British citizens living in Europe at 310,000
The Republic of Ireland at 250,000
France at 190,000
Germany is around 106,000
Italy at 26,000
As we've said figures vary somewhat between different data collecting and monitoring organisations but the proportion of Brits in different countries in the EU remain roughly the same.
