The Bulgarian ambassador has told ITV News there should be no panic about an influx of Bulgarians as many of them who want to work in the UK have already arrived in the country.
Figures released by the Office for National Statistics suggest the number of Romanians and Bulgarians working in the UK has risen by more than a quarter in three months.
Ambassador Konstantin Dimitrov said, "I think it is unnecessary for the simple reason that most of those who want to come here have already done so".
