Poland’s deputy prime minister, who until now had led a junior party in the government, has lost his position as head of his Polish People’s Party, raising questions about the government’s continued make-up.
Waldemar Pawlak was replaced as head of his small, agrarian-based party at a party congress.
After the vote Mr Pawlak said he intends to give up his government posts.
Aside from deputy prime minister he also holds the portfolio of economy minister. However, the new party leader, Janusz Piechocinski, urged Mr Pawlak to remain in the government.
Government spokesman Pawel Gras said the development would most likely lead to coalition talks next week.
The Polish People’s Party has served since 2007 as the junior partner in a government led by prime minister Donald Tusk’s Civic Platform.
