The fact-finding committee into the luxury watches worn by Deputy Prime Minister Prawit Wongsuwon will present its findings to the National Anti-Corruption Commission (NACC) on Thursday.

NACC secretary-general Worawit Sukboon said Monday the panel has scrutinised a 38-page written explanation of the 39.5-million-baht collection submitted by Gen Prawit.

The NACC will decide on Thursday whether to summon Gen Prawit to appear in person to make a statement, Mr Worawit said.

"Now that Gen Prawit has presented his clarification, if the NACC feels the information is still incomplete, it will ask him to provide further details," Mr Worawit said.

The saga over Gen Prawit delaying providing his explanation started when the first deadline passed on Jan 8, after that it was repeatedly extended leading to criticism that the NACC was stalling the inquiry.

The NACC has claimed that because of the growing number of watches exposed on social media, the commission needed more time to investigate. It also claimed that to be fair it also had to give Gen Prawit more time to gather evidence.

The luxury watches were not declared among his assets to the NACC and Gen Prawit claimed they all belonged to friends and have since been returned to their owners.
