Thai Prime Minister Thaksin Shinawatra, deposed this week by a military coup, left office tarnished by allegations of corruption and abuse of power.  His ungraceful exit is in stark contrast to the high hopes many had when he took office in 2001.

Thaksin Shinawatra, a former policeman and telecommunications tycoon, was elected to office in 2001 by a landslide. He often extolled the virtue of business management in his approach to government.

His chief executive officer style was applied from cabinet meetings to the local government level, where he called on governors to apply skill to delivering services to local communities.

It wasn't long after the Thai Rak Thai party that he founded won election, however, that Mr. Thaksin's critics were accusing him of arrogance and authoritarianism. In an address in 2003, he answered his critics.

"Under a democratic system you have to make it clear, you have to make it strong and push it. This is not authoritarian. Under a democratic system how can I be authoritarian? [But] If you try to make democracy, at the end you will run a country by playing politics everyday," he said.

At the time of Mr. Thaksin's first victory, the Thai economy, bruised by Asia's financial crisis of the late 1990s, was in need of a strong leader.

After the election, he quickly began implementing populist policies aimed at the poor, including subsidized public health programs, low-cost loans for the rural poor and village-based micro-industries.

His brusque manner made him unpopular among politicians, academics and the middle class in Bangkok, but his policies were extremely popular in the countryside. He easily won election again earlier this year, despite the allegations against him, and many of the people he helped have expressed dismay at his being thrown out of office.

Thitinand Pongsutthirak, a political scientist at Chulalongkorn University, has been critical of Mr. Thaksin. But he concedes that the prime minister did make positive contributions during his time in office.

"The focus on the rural poor, the rural grass roots, the urban poor - his restructuring of the bureaucracy was done when it was needed. So he left a very mixed legacy. I would say 95 per cent is not good - but don't forget the five percent," said Pongsutthirak.

Street protests against Mr. Thaksin's policies began in Bangkok in late 2005, and evolved into outright calls for his resignation in January, after his family's tax free-sale of nearly $2-billion worth of stock in the company he founded.

Chulalalongkorn University's Thitinand said that act became a key factor leading to Thaksin's downfall.

"The reasons for the coup was Thaksin's lack of legitimacy stemming from the charges we've seen all throughout the year - constitutional violations, corruption, conflict of interests, abuses of power, selling state assets to foreign companies," he continued. "These are charges that Thaksin has not answered."

But Thitinand believes Thaksin may yet attempt to make a return to Thai politics.

"Thaksin's support runs deep - it's extensive, it's widespread," added Thitinand. "And we have to admit that he's done something that no one else in Thailand has done - he has made himself very popular to a majority of the Thai people."

Mr. Thaksin was in New York for the United Nations General Assembly when the coup took place. He is now in London, where he released a statement Thursday calling for "national reconciliation," and urging all parties to work together for the sake of the Thai king and country.

It was a typically flamboyant gesture from a forceful politician who has not yet admitted that he has lost.
