The figures showed that the number of EU citizens employed in Britain nearly doubled during the period when David Cameron was prime minister.
They rocketed from 1,195,000 in 2010 to 2,235,000 this year, a rise of 87%.
Employment for Bulgarians and Romanians in the UK has more than doubled, according to the figures.
Around 130,000 citizens from the two former communist nations were working in Britain in January 2014 when visa restrictions for travel to the EU from both countries were lifted.
By last month, the figure was 266,000 and up from 228,000 recorded in the same period in 2015.
