BANGKOK (Reuters) - Thailand's Constitutional Court on Friday annulled last month's general election, leaving the country in political limbo without a full government and further undermining a prime minister faced with impeachment over a failed rice subsidy scheme.

Weakened by five months of unrest, Prime Minister Yingluck Shinawatra is expected to defend herself before an anti-corruption commission by March 31, and a decision to seek her impeachment could come soon after that, with the Senate expected to take up the matter quickly.
