* EU presidency, economic crisis, budget are priorities
* Fischer's EU role seen difficult (Adds analyst quotes, background)

PRAGUE, April 9 (Reuters) - Czech President Vaclav Klaus appointed non-partisan Jan Fischer as prime minister on Thursday following a political crisis in the ex-communist country halfway through its European Union presidency.
Fischer will take over from Mirek Topolanek on May 9, replacing his centre-right minority government after it lost a March 24 no-confidence vote initiated by the leftist opposition.
Fischer will start picking his ministers next week and his administration, to be made up of non-party experts, will lead the country until early polls planned for October.
"This government will have to cope with the EU presidency ... and within its capabilities mitigate the impact of the economic crisis," Fischer, head of the country's statistical office, said following his appointment.
He said the government would also have to prepare the 2010 budget, a key task because the country's fiscal gap threatens to jump above 4 percent of gross domestic product both this year and next as revenues fall and parliament plans tax cuts and extra spending.
Topolanek, who cut income taxes, raised the retirement age and tightened the budget, is stepping down after losing the no-confidence vote. It had been backed by the opposition and several rebel deputies, toppling his faction-ridden cabinet.
Fischer's new cabinet will be supported by the two biggest political parties, Topolanek's right-wing Civic Democrats and the opposition Social Democrats, who together control three quarters of seats in the lower house of parliament.
Fischer said he had no political ambitions and wanted to return to the statistical office following the October election.
EU ROLE SEEN TOUGH TASK
Analysts say Fischer should not face major obstacles tackling the economic turmoil after parties from the outgoing coalition and the leftist opposition Social Democrats agreed on Wednesday to support a set of compromise measures to combat the crisis. [
]But they warned the EU presidency, tarnished by the last government's collapse, would be a tough task because Fischer is an outsider with no political weight.
"European politicians will not see him as an equivalent partner with whom they communicate on an everyday basis," said Pavel Saradin, a political science lecturer at Palacky University in Olomouc.
Fischer's administration should keep close ties with the old one through deputy ministers, he said.
"I expect a close cooperation with deputy ministers... and creation of some kind of a communication platform that would include the old administration, with Fischer working as a mediator between the two environments rather than someone to make big decisions."
The new cabinet's EU role, ending on June 30, will probably be limited, given it will lead the bloc for under two months.
Fischer is a media-shy and cautious man who rarely speaks in public. He was a member of the Communist party in the 1980s, like many professionals who sought to further their careers.
President Klaus -- a Eurosceptic who has repeatedly played down the significance of the EU presidency -- said he had no doubt the Czechs would complete it without any problems. (Writing by Jana Mlcochova; Editing by Charles Dick)
