Greece's caretaker cabinet was sworn in Thursday and will lead the country into next month's election, after a deadlocked vote sparked more political turmoil and brought the country's use of the euro currency into question.

The 16-member cabinet was sworn in during a ceremony in the presidential mansion in Athens, followed by the swearing-in of parliament's 300 legislators, who will take their seats for just one day before the body is dissolved for the new vote.

The parliamentarians were elected in the May 6 vote, which left no party with enough votes to form a government. Coalition talks collapsed after nine days.

Among the legislators who took their seats for the day were 21 from the extremist right-wing Golden Dawn party, which vehemently rejects the neo-Nazi label. The party campaigned on pledges to rid Greece of immigrants and clean up crime-ridden neighbourhoods. It also advocates planting landmines along Greece's border with Turkey to stop more immigrants entering the country.

The party won nearly 7 per cent of the vote on May 6, a massive increase from the 0.31 per cent it had won in the 2009 parliamentary election.

The cabinet sworn in Thursday is led by Council of State head Panagiotis Pikrammenos, a 67-year-old judge appointed Wednesday as Greece's interim prime minister.

U.K. PM urges end to euro crisis

In London Thursday, British Prime Minister David Cameron on Thursday urged Europe to sort out its currency crisis, calling on the 17-country eurozone "to make-up or it is looking at a potential break-up."

"Either Europe has a committed, stable, successful eurozone with an effective firewall, well capitalized and regulated banks, a system of fiscal burden sharing, and supportive monetary policy across the eurozone. Or we are in uncharted territory which carries huge risks for everybody," Cameron said in a speech in Manchester.

Cameron said that if Greece is forced out of the single currency union, the possible collapse of the eurozone poses huge risks to the U.K. economy, but he said Britain was prepared to weather the fallout.

"Whichever path is chosen, I am prepared to do whatever is necessary to protect this country and secure our economy and financial system," Cameron said.
