Asian markets tumbled on Tuesday, bringing a recent rally to a juddering halt, as Wall Street and European shares were hit by political concerns in Spain and Italy.
The euro also slumped as Spain's prime minister was forced to deny corruption claims, while former Italian premier Silvio Berlusconi vowed to throw a spanner in the works of a government austerity drive ahead of a general election.
Tokyo shares dived 1.90 percent, or 213.43 points, to 11,046.92, while Seoul slipped 0.77 percent, or 15.03 points, to 1,938.18 and Sydney shed 0.51 percent, or 24.8 points, to 4,882.7.
In the afternoon Hong Kong tumbled 1.54 percent but Shanghai reversed morning losses and was up 0.39 percent.
The losses come after several markets approached highs not seen for several months as confidence slowly returns, thanks to an easing of the eurozone debt crisis and a pick-up in the US and Chinese economies.
However, dealers suffered a blow Monday when Spanish Prime Minister Mariano Rajoy came under pressure to step down as he becomes engulfed in a corruption scandal.
Rajoy has dismissed claims by Spain's El Pais newspaper that he and other ruling party officials channelled donations into secret payments.
The news sent the Spanish cost of borrowing surging, reviving worries about Madrid's ability to access the debt market to keep functioning.
Berlusconi meanwhile said he would refund the money Italians have had to pay for an unpopular property tax if his coalition, headed by his protege Angelino Alfano, wins a February 24-25 election.
Recent polls have shown his party making solid gains.
Berlusconi, who would take the role of finance minister in a new government, abolished the real estate tax in 2008 but it was reinstated last year as part of Prime Minister Mario Monti's austerity budget in Italy.
