Polish Prime Minister Donald Tusk, left and Deputy Prime Minister Janusz Piechocinski listen to lawmakers in the parliament in Warsaw, Poland, Wednesday, June 25, 2014.
Poland's prime minister has asked lawmakers for an urgent vote of confidence in his government, which has been rocked by leaked tapes of private conversations of top state officials.
Donald Tusk said in parliament on Wednesday that without renewed support he will not be able to effectively represent Poland in the European Union.
The timing of the vote was not immediately decided.
Tusk suggested that foreign interests might be involved in eavesdropping on ministers and high officials. He did not name any country, but said businessmen trading coal and gas from Russia were being investigated.
Eavesdropping carries up to two years in prison in Poland. Two restaurant employees have been charged in the case and two businessmen were detained for questioning.
