PRAGUE (Reuters) -Czech Prime Minister Petr Fiala proposed the dismissal of Development Minister Ivan Bartos on Tuesday, a surprise move that shook the centre-right coalition and likely means the exit of the smallest party.

The Czech Republic's government was in crisis Tuesday after a junior party in the ruling coalition said it would leave the Cabinet over Prime Minister Petr Fiala’s decision to fire the party leader. Fiala said he would ask the president to dismiss Regional Development Minister Ivan Bartos by the end of the month.

Czech Prime Minister Petr Fiala moved to replace a cabinet minister from a junior ruling party in a sign of mounting tension within the coalition government after its defeat at last week’s regional elections.

Czech Prime Minister Petr Fiala said on Tuesday he would propose the dismissal of Development Minister Ivan Bartos, who heads a junior ruling party, from the cabinet due to problems in digitalising the state system of issuing building permits.
