1. Pojaman Shinawatra's Ratchadapisek land purchase

The couple would be charged with violating Article 152 of the Criminal Code for allegedly exploiting Thaksin's position for personal gain. The AEC had earlier charged Thaksin and Pojaman with violating Article 100 of the National Counter Corruption Commission Act that bans state officials and their spouses from having an interest in contracts made with state agencies under their supervision.

The AEC has decided to press for additional criminal charges against Thaksin and Pojaman over the controversial land purchase, which could result in the plots in question being seized.

2. Alleged tax evasion in the share sale of Shinawatra Computer and Telecommunications

The Office of Attorney-General has decided to prosecute Pojaman, her brother Bhanapot Damapong, and her private secretary Kanchanapa Honghern for tax evasion.

In 1997, Bhanapot received 4.5 million shares of Shinawatra Computer and Communication worth Bt738 million from Shinawatra household maid Duangta Wongpakdi, as a wedding gift from Khunying Pojaman Shinawatra, allegedly to avoid taxation.

The next step is for the AEC to summon the defendants to report to prosecutors before March 26 to hear the charges against them.

3. Alleged tax evasion in Shin Corp share sales to Temasek Holdings

March 16: Surin Upapatkun, the major shareholder of Kularb Kaew Co, outlined his involvement in the company, while many suspect the company acted as a nominee for Singapore's Temasek Holdings to execute the Shin Corp deal in 2006.

The AEC fact-finding committee is gathering information about the share sale by Thaksin's children Panthongtae and Pinthongta.

4. Procurement of CTX9000 bomb scanners and baggage-handling system for Suvarnabhumi Airport

The case is under investigation and summonses have been sent to 38 people. Former prime minister Thaksin Shinawatra is scheduled to testify on March 29, and on the same day former transport minister Suriya Jungrungreangkit would report to the AEC to hear the allegation.

5. Krung Thai Bank Loan

The AEC subcommittee has said that 32 people, including Thaksin's son Panthongtae and five companies, were involved in the loans, which is estimated to have cost the state up to Bt4.5 billion.

6. BMA fire-fighting vehicles and boat procurement

Former Bangkok governor Samak Sundaravej, ex-interior minister Bhokin Bhalakula and his deputy Pracha Maleenont are among five people to be investigated by the AEC for alleged involvement in the corruption scandal.

The AEC has incriminated 32 former cabinet members of the Thaksin government and 17 officials for state losses of Bt15 billion in taxes from the two- and three-digit lotteries.

8.Rubber-sapling purchase

More than 70 people, including all members of the Thaksin cabinet, are accused of being involved in the sapling corruption scandal.

The case is now being probed by AEC's investigation subcommittee. The panel is hearing clarifications by the accused.

9. Power scandal at Suvarnabhumi Airport

The AEC has appointed an investigation panel while the Airports of Thailand has sent representatives to the AEC to lodge a complaint against 14 suspects, including former transport minister Suriya Jungrungruangkit, and Srisook Chandrangsu, then permanent secretary at the transport ministry, for alleged involvement in the purchase of the underground power line system.
