Finland's National Coalition Party has voted to replace finance minister Alexander Stubb as leader, hoping to revive flagging support for the centre-right group that is part of the government elected last year.
At a party congress, 441 delegates voted in favour of replacing Mr Stubb with Interior Minister Petteri Orpo while 361 backed keeping him as NCP chief.
As a result, Mr Orpo is expected to become finance minister as well.
Mr Stubb, who also served as prime minister in 2014-15, has faced growing criticism both for his party's poor showing in the polls and for compromises made in the three-party government.
He has also drawn fire for his image and leadership style.
