Thailand's Supreme Court has sentenced former Manchester City owner Thaksin Shinawatra to two years in prison after finding him guilty of violating a conflict-of-interest law while prime minister.

The nine judges ruled by five to four that Thaksin, who has been at the heart of Thailand's political crisis over the past three years and now lives in exile in Britain, had got involved in his wife's purchase of land from a central bank fund.

"The defendant is guilty of violating the anti-corruption law, and the punishment is two years in prison," a judge said, reading out the verdict.

Thaksin, speaking by telephone, said the case was politically motivated. He has said before that he could not expect a fair trial from Thai courts. "I have been informed of the result. I had long anticipated that it would turn out this way," he said.

He denied British media reports he was seeking asylum in Britain. A Thai prosecutor said he would urge Britain to extradite Thaksin now that the court had sentenced him to prison.

The ruling is the first on a spate of corruption charges against Thaksin and his political associates prepared by investigators appointed after a military coup in 2006.

Thaksin recently sold Manchester City to an Abu-Dhabi based group.
