Thailand's prime minister is set to discuss with the country's polling body the possibility of postponing a general election set for Sunday.

Election Commissioner Somchai Srisutthiyakorn said Tuesday that the election should be cancelled due to potential violence ahead of the vote.

Last week, the Constitutional Court ruled the parliamentary poll can legally be delayed. But it said the power to do so rests with the prime minister in consultation with the Election Commission chief.

The caretaker government had said the date was unchangeable.

Already, hundreds of anti-government supporters have surrounded the location where caretaker Prime Minister Yingluck is scheduled to meet Election Commission official.

On Sunday, one protester was shot dead in a clash, as protesters swarmed dozens of polling stations in Thailand to stop advance voting.
