BANGKOK - THAI Prime Minister Somchai Wongsawat said on Friday he was considering building a new headquarters in Bangkok as anti-government protesters continue a three-month siege of his office.

Mr Somchai, the brother-in-law of ousted premier Thaksin Shinawatra, has been working with his cabinet from an abandoned airport terminal since demonstrators seized his offices in August.

Supporters of the People's Alliance for Democracy (PAD) have since refused to budge from Government House until Somchai's administration resigns, accusing it of acting as a corrupt proxy for the exiled Thaksin.

'It's been a very long time so we should find a new place, but I have not yet consulted anyone or begun looking at any particular place,' Mr Somchai told reporters.

'Government House is a bit old and once the protesters are out it will take time to renovate,' he said.

Mr Somchai said Government House could become a museum or political archive office.

'It's just my idea. I have to discuss with many senior people,' he said.

'But it will be in Bangkok, I will not move it up-country,' he added, referring to the northern city of Chiang Mai, Thaksin's hometown, where the government continues to enjoy strong support.

Thailand has been in crisis since telecoms billionaire Thaksin was ousted in a military coup in September 2006, following protests that were also led by the PAD.

Thaksin's allies in the People Power Party (PPP) won elections in December, angering the old power cliques in the palace, military and bureaucracy who tried to rid Thailand of Thaksin's influence.

Parliament elected Mr Somchai as prime minister on September 17 after his predecessor Samak Sundaravej was forced from office by a court that ruled he had been illegally paid for hosting TV cooking shows.

The PAD's movement erupted into violence on October 7 when police fired tear gas at thousands of protesters trying to block parliament. Two people were killed and nearly 500 injured in the resulting clashes. -- AFP
