But although July's jobless rate fell to 15.7% from 16% in June, it is still the highest in the European Union.

The government has worried about Poles leaving to work in other EU countries since Poland became a member in 2004.

The officials - who are worried about the brain drain seen in recent years - are planning on visiting the bars and pubs frequented by Poles in London to try to lure them back.

"Some people have found work in social jobs subsidised by the state Labour Fund. Many have also left the register of unemployed because they have left for work abroad," said the Labour Ministry on Friday.
