THAI Prime Minister Abhisit Vejjajiva has been receiving over 100 intimidating phone calls a day since his election, said his aide.

Mr Sirichoke Sopha, an aide to the premier, said hate calls were made to Mr Abhisit's mobile phone about 100 times a day since the House elected him prime minister, the Nation reported on Monday.

Mr Sirichoke said Mr Abhisit mostly takes the calls himself and tries to explain his election to the callers.

He said most callers used rude and abusive language and got hold of Mr Abhisit's mobile phone number from the taxi drivers' community radio station.

Mr Abhisit, Thailand's third prime minister in four months, has promised in his policy speech to heal the country's deep rifts and restore its international image.

He was forced to delay his speech by a day because of the protesters outside Parliament - the same street-swamping tactics that anti-Thaksin protesters had used before he came to power two weeks ago.

Mr Abhisit was formally named prime minister on Dec 17 in a step that many hoped would bring peace.

In a New Year's message, Mr Abhisit called on Thais to settle their differences in the coming year.

Thailand has been rocked by protests by rival groups of demonstrators who either support or oppose the former premier Thaksin Shinawatra, once one of the country's richest men, who now lives in self-imposed exile after being forced from office in a 2006 military coup for alleged corruption.
