Slovakia's Prime Minister Eduard Heger said on Sunday he had asked the president to relieve him of his duties, after ministers' resignations weakened his cabinet which is serving in a caretaker capacity before elections in September.

Heger is due to meet President Zuzana Caputova, who has the power to appoint a new prime minister, later on Sunday.
