Most are core members of the so-called House No.111, which refers to the 111 former executives of the now- defunct Thai Rak Thai Party who on May 30 finished serving a five-year ban from politics. Others are government officials who previously worked closely with the Thaksin government.
Among this group of Thaksin loyalists is Pansak Vinyarat, who was said to be the brains behind both of Thaksin's tenures. He was the person behind the creation of many political, economic, and social policies of the Thai Rak Thai regime.
The well-known set of economic development policies _ better known as Thaksinomics _ was Mr Pansak's brainchild, as was the populist policy of turning national assets into sources of state funding.
Now, Mr Pansak, who was officially a key adviser to Thaksin in the past, has started serving as a key adviser to Prime Minister Yingluck Shinawatra. It remains unclear what policies Ms Yingluck has assigned him to work on.
Meanwhile, Pol Maj Gen Attagrit Tharechat, a former head of Thaksin's security team, in June emerged as the director of the Government Lottery Office (GLO). With Gen Attagrit at the helm, it is believed the government wants to push its two- and three-digit lottery, or online lottery, project through.
It is believed the lottery will be used as a tool to generate income to help fund the Yingluck administration's populist policies. In the few months after Pol Maj Gen Attagrit took the director's seat of the GLO, the online lottery project has quickly taken shape. He has said he hoped to see the project start by next year.
Atthawich Suwanphakdee, Democrat MP for Bangkok, said the project was scrapped by the Abhisit Vejjajiva government because the party opposed legalising what was an underground lottery.
The Thaksin government had attempted to make the online lottery happen, yet was initially unsuccessful because the move was deemed a violation of the government lottery law.
The Thai Rak Thai government dodged that legal obstacle by using a different Interior Ministry law regarding gambling.
Under that law, the Thaksin government would be allowed to implement its lottery project as long as revenue was not put into state reserves, Mr Atthawich said.
Phumtham Wechayachai was another top man in the Thaksin government who has returned as a key figure in the Yingluck administration. He was recently appointed the director of Pheu Thai, and is now adopting the same development model that worked well with Thai Rak Thai.
Mr Phumtham is leading a regrouping of the party's political base, with the goal of increasing the number of party members to at least 15 million _ the same figure Thai Rak Thai once boasted.
With the increasing popularity of new media, Mr Phumtham is also eyeing the internet as an important channel for Pheu Thai MPs to reach supporters.
He plans to resume the youth council project, which had 10,000 members during the Thai Rak Thai regime.
"More work to fine-tune Pheu Thai is on the way," Mr Phumtham said.
Pokin Polakul and Pongthep Thepkanchana, two of Thaksin's key legal advisers, are also leading a coalition government team to develop a framework for amending the constitution.
The pair are responsible for resolving the legal deadlock facing the government's bid to amend the charter. But they have so far failed to persuade many politically neutral legal experts to get involved in the government's charter rewrite bid, according to Somchai Srisuthiyakorn, a political science lecturer with Sripatum University.
Many capable people wanting to join the team have been blocked from doing so by House No.111 figures and Thaksin's close aides, who are consolidating their control. Mr Somchai said anyone who works for Thaksin must be aware that they cannot be independent or refuse to follow orders.
