Thailand constitution writers have decided to ban the "unusually rich" from their parliament and senate.

On Friday, they reviewed the qualifications for holding political office, spokesperson of the Thai Constitution drafting committee general Lertrat Rattanavanich was reported as saying by The Bangkok Post yesterday.

Under their new decision, politicans who have been removed from office for four offences will be banned from becoming MP or joining the senate.

According to the report, the four offences are "being unusually rich", "acting in ways that indicate corruption against their duties", "acting in ways that may demean public office" and "acting in ways that indicate corruption against judicial positions".

Anyone who has been judged by a court or a legitimate order to have caused an unfair election is also banned for life.

Additionally, one could be banned for five years if they are found to have committed minor offences.

The constitution writers have described minor offences as "acting unethically", "falsely declaring assets" or "having been removed from office for using their powers in violation of the constitution or laws".

In Section 35 (4) of the Thai interim charter, general Lertrat has said that the constitution drafters are required to put mechanisms in place to ban corrupt politicans for good.

These new provisions have led to speculation that former Thai prime ministers and siblings Thaksin and Yingluck Shinawatra will be forced out of the political scene for good.
