UPDATE 1-Czech president may name new PM soon - analysts

(Adds president calls news briefing paragraph 4)

By Alan Crosby

PRAGUE, Nov 6 (Reuters) - Czech President Vaclav Klaus may name a new prime minister after his proposal for a "rainbow coalition" government failed to force an end to a five-month stand-off in parliament.

On Friday Klaus proposed to leaders of the five parties in parliament an interim solution to create a government after a June election ended in deadlock with centre-right and leftist parties each winning 100 seats.

Klaus gave the parties until Tuesday to decide, but the leftist Social Democrats rejected the move and other parties have been lukewarm to the proposal, which sees the broad coalition ruling for a limited time and then early elections.

Klaus called an extraordinary news conference for 3 p.m. (1400 GMT). His office said the president would make "an important statement on the current political situation".

Klaus's spokesman Petr Hajek said earlier the president might "launch his own initiative".

Hajek would not elaborate, but analysts said Klaus might soon pick a new prime minister -- either a politically unaffiliated expert or a party leader.

"The responsibility for proposing a workable government is falling on his shoulders, but his options are almost gone ... Klaus must put concrete chips on the table," said political commentator Erik Best.

"No one knows what Klaus will do, but a radical move that re-establishes his own position, wins the Social Democrats' sympathy, and throws the (rightist) Civic Democrats off guard can't be ruled out. Klaus could perhaps achieve this by appointing Jiri Paroubek today or tomorrow."

Paroubek, whose Social Democrats came second in the election, has long wanted to be prime minister and stepped up his calls for Klaus to ask him to form a government after rightist Prime Minister Mirek Topolanek was appointed and then failed to win a parliamentary vote of confidence.

Klaus has said he will not appoint a government that would rely upon one or two deputies who cross the lower house floor, and Paroubek has not said where he would get a majority.

Paroubek, who ruled for around a year until the election, insists on being given a chance by being nominated either by Klaus or the house speaker.

"In civilised countries it is normal to give an opportunity to the chairman of the second strongest party in case the election winner fails," said political commentator Jiri Hanak.

Topolanek, buoyed by the dominance of his Civic Democrats in recent Senate and municipal votes, wants new elections early next year.

If two governments fail, the leader of the third is chosen by the house speaker. If a third government fails, the president can call early elections within 60 days. Otherwise, parliament needs a three-fifths majority vote to dissolve itself and trigger an election.
