The number of Romanian and Bulgarian workers in the UK rose by a quarter in three months, according to official statistics.
The Office for National Statistics said 141,000 were employed from April to June compared with 112,000 in the previous three months.
The government has not said how many more migrants it expects once the labour market is open fully to the two countries later this year.
