Polish Prime Minister Jaroslaw Kaczynski has sacked Interior Minister Janusz Kaczmarek amid a deepening government crisis.
Mr Kaczynski told reporters there were suspicions Mr Kaczmarek had leaked classified information, obstructing an inquiry into alleged bribery. Kaczynski said Wladyslaw Stasiak, who heads the president's National Security Council, would replace Mr Kaczmarek.
He repeated that an early poll might be unavoidable as a result of the crisis.
On 5 August, the Self-Defence Party, a junior member of the governing coalition, withdrew its two ministers out of the cabinet.
Mr Kaczmarek, a former chief prosecutor, was appointed only in February, after his predecessor, Ludwik Dorn, resigned following a dispute with the prime minister.
'If there is no parliamentary majority, new elections are unavoidable' said Kaczynski.
'I am in favour of a swift election because we face a destructive opposition ... There is no point in prolonging things'.
According to the Polish constitition, the next general election is not due until September 2009.
