Slovakia's Interior Minister Robert Kalinak has resigned amid a political scandal caused by the murder of a journalist and his fiancée, BBC reports.
Mr Kalinak bowed to pressure from a junior coalition partner and quit his posts, stripping Prime Minister Robert Fico of a key ally.
His is the third resignation in a matter of weeks.
Reporter Jan Kuciak was investigating government corruption when he and fiancée Martina Kusnirova were killed.
The killings have gripped Slovakia, leading to calls for an investigation and to anti-government protests in Bratislava on Friday which were thought to be the largest in the country since the fall of Communism in 1989.
