Over 3,000 policemen are expected to protest outside the Prime Minister's Office, at noon, Tuesday. 

Police trade union members are demanding payment of arrears and plans to reduce the police budget for next year.

President of the trade union in Lodz, Zbigniew Jagiello, says that he will be handing in a petition to Prime Minister Donald Tusk.

The protest is expected to last around three hours. (pg)
