PRAGUE, May 8 (Reuters) - Czech President Vaclav Klaus appointed a caretaker administration on Friday which will complete the central European country's term as European Union president and lead it to an early election in October.
The appointment of the technocrat cabinet led by new Prime Minister Jan Fischer, the country's chief statistician, ends a political crisis sparked by a parliamentary no-confidence vote which overthrew the centre-right administration of Mirek Topolanek in March.
The Czech Republic, a country of 10.5 million, has seen its export-driven growth collapse and is grappling with economic decline, forecast by the Finance Ministry at 2.3 percent this year.
"Today's economic situation requires that we have a functioning and an efficient government and I believe that you will be such a government," Klaus told the new ministers at the Prague Castle after appointing them.
The prime minister said he would focus on completing the EU presidency ending in June and drawing up the 2010 state budget, a tough task amid an economic downturn.
"I am going to prepare, with my colleagues, a state budget that is very austere... because anything else would mean serious macroeconomic difficulties with consequences in the following years," he said ahead of the cabinet's first session.
Fischer's team will stay on for less than six months and has no legislative ambitions, keeping in place liberal economic reforms of the Topolanek administration including a flat 15 percent personal income tax rate.
The prime minister has said he wanted to leave all important decisions on the next government coming from the early election, which will have a stronger political mandate.
CONFIDENCE VOTE
The government will be dependent on parliamentary backing from Topolanek's centre-right Civic Democrats and the leftist Social Democrats, the biggest political parties that will fight out the autumn election.
Fischer is a pick of both the biggest parties and his cabinet is expected to win confidence in the evenly-split lower house, a motion that must come within 30 days.
President of the European Commission Jose Manuel Barroso congratulated Fischer on his appointment and said the commission would help during the rest of the EU presidency.
Analysts warned Fischer would have to face a possible pre-election spending spree endorsed by main parties, which could bloat the budget gap next year above the 4.5 percent of gross domestic product forecast by the Finance Ministry for 2009.
The ministry's veteran budget expert and new Finance Minister Eduard Janota said he wanted the 2010 central state budget -- the main part of the overall public sector balance -- with a deficit smaller than 150 billion crowns ($7.55 billion), which the government targets this year.
This would put the overall 2010 public sector deficit at 4.6-4.7 percent of gross domestic product. Without savings measures, the gap would jump to 6.7 percent, Janota had said.
Janota had said Fischer's cabinet would not push ahead with plans to adopt the euro currency due to the swelling budget gap.
Stefan Fuele, 46, the Czech ambassador to NATO, takes over from Alexandr Vondra as European affairs minister. Deputy Foreign Minister Jan Kohout, 48, replaces Karel Schwarzenberg as foreign minister.
