BANGKOK, THAILAND - THAILAND'S army commander General Anupong Paochinda said on Wednesday a government drive to amend the military-designed 2007 constitution would prolong the country's political crisis.

Gen Anupong, a member of the military council that ousted Prime Minister Thaksin Shinawatra nearly two years ago, said charter amendments sought by current Prime Minister Samak Sundaravej would hinder his government's effectiveness.

'I can't say whether I agree or disagree, but I am concerned that a bid to amend the charter will prolong the political conflict, which will hamper the government's ability to tackle the country's problems,' he told a Thai television station.

With his government threatened by a series of legal cases that cost him two cabinet ministers last week, Mr Samak has blamed his troubles on the constitution, which gave judges more oversight powers in the political arena.

The charter rejig was first floated months ago, but shelved after anti-government groups launched a street campaign in May.

Critics accuse Mr Samak of seeking the changes to protect Thaksin from corruption charges and perhaps pave the way for his return to power.

Mr Thaksin, who was barred from politics along with 110 other top members of his banned Thai Rak Thai Party, has repeatedly said his political days are over. But most Thais believe he is still pulling strings from behind the scenes.

'Many parties are suspicious that such a move will benefit a particular group. The government has to clear up that suspicion,' Gen Anupong said of the proposed charter changes which Samak has yet to define.

Gen Anupong, who has said coups are no longer a way to solve Thailand's political problems, said any charter amendments would need a wide range of public consultation. -- REUTERS
