The National Anti-Corruption Commission (NACC) is investigating the land owned by about 60 MPs.

NACC secretary-general and spokesman Niwatchai Kasemmongkol made the remarks in response to calls for the NACC to speed up its probes against MPs in cases which could be similar to that of Pareena Kraikupt, the former Palang Pracharath (PPRP) MP for Ratchaburi banned from politics for life.

Ms Pareena was banned on April 7 by the Supreme Court for wrongly possessing state land.

Mr Niwatchai said the NACC is investigating land ownership of some 50-60 MPs.

In response to Mr Niwatchai's comments, Ms Pareena posted on Facebook on Monday that the court's ruling against her has made it clear that politicians could not occupy state land and doing so was a serious violation of the code of ethics.

She also called on the NACC to speed up its investigation into land owned by the 60 MPs, without bias.
