意总理恩里科・莱塔将辞职
Italian Prime Minister Enrico Letta has said he will resign on Friday.
意大利总理恩里科·莱塔称他将于周五辞职。
Mr Letta had only been in post for ten months
Party leader Matteo Renzi had earlier called for a change of government at a party meeting, saying the country could not go on in "uncertainty".
Speculation has been rife that Mr Renzi wants to take over as prime minister.
He is eight years younger than Mr Letta and was elected leader of the party in December.
Mr Letta said in a statement that his decision followed "the decision taken today by the national leadership of the Democratic Party".
He said he would formally submit his resignation to President Giorgio Napolitano at the presidential palace on Friday.
Relations between Mr Letta and Mr Renzi had become increasingly fraught, the BBC's Alan Johnston reports from Rome.
The Democratic Party now hopes that Mr Renzi will be able to replace him, and form a new administration, our correspondent adds.
