Prime Minister Yingluck Shinawatra's ruling Pheu Thai Party will probably drop plans to completely rewrite the constitution, amending it section-by-section instead to avoid challenges that caused previous governments to fall, Thaksin said in Singapore on Monday."If we cannot amend the constitution that we have now, it's difficult," said Thaksin, who has lived overseas since fleeing a 2008 jail sentence. "It's like the government is living in a house full of land mines. So you have to be very cautious."The approach may extend the tenure of Ms Yingluck's 13-month-old government, which has already outlasted the last Thaksin-linked administration that collapsed in 2008 after yellow-shirt protesters seized Bangkok's two airports.The government will push to change the charter even after the Constitution Court ruled in July that a referendum should be held before the document is overhauled.Planned amendments would decrease the power of independent agencies such as the Constitution Court and give more say to elected officials, Thaksin said.Thaksin's opponents, who accused him of using government agencies to attack his political foes while he was in charge, say his proposed changes will allow him to recoup his seized fortune and return to Thailand without spending time in jail.In 2008, Thaksin fled abuse of power charges for helping his then-wife buy land from the government.In 2010, a court seized 46.4 billion baht held by Thaksin's family after ruling that policies during his five years as prime minister increased the value of Shin Corp, the telecommunications company now controlled by Temasek.Thaksin declined to reveal his net worth."The principle is about justice," Thaksin said, referring to his seized wealth. "Did I have enough justice? Did they treat me correctly? Did they observe the rule of law? If not, I have to be remedied."Two weeks after his cash was seized, the Thaksin-backed red shirts began protests that shut down Bangkok's commercial centre and led to a crackdown by the Democrat-led government of the time that left 92 people dead.Thaksin said bills granting an amnesty for political offences from all sides since the coup would remain tabled in parliament as more discussions are held.At the same time, he said the previous government, headed by Abhisit Vejjajiva, should face trial for setting up live ammunition zones to besiege protesters in 2010."It's too much, the way they cracked down on the people," Thaksin said, adding that the International Criminal Court is considering whether to accept a petition filed by the red shirts.Democrat spokesman Chavanond Intarakomalyasut said Mr Abhisit and other Democrat members are willing to face the courts to establish the truth.He cited a report by the Truth for Reconciliation Commission that also blamed militants hiding within the protesters for some of the deaths."Thaksin is always speaking outside the country," Mr Chavanond said."Why doesn't he come back and prove what really happened and prove to the people that he's innocent?"The reconciliation commission, set up by the Abhisit government after the violence, cautioned against a broad amnesty and called for constitutional changes to be explained to the public, as well as for the military to stay out of politics and for judges to remain neutral.When releasing its report, commission chairman Kanit na Nakorn called for Thaksin to stay out of political affairs. "That's the view of a very few people," Thaksin said, adding that "Kanit is still angry with me about a dispute over who to include in the Thai Rak Thai party", which brought him to power in 2001.Mr Kanit declined to comment Tuesday on Thaksin's remarks."I respect all who make comments on our report," Mr Kanit said. "It's a good opportunity for public accountability."Thaksin Tuesday left Singapore for Brunei to give his congratulations for the wedding of the daughter of the Sultan of Brunei.
