A Police Commission meeting will be held today to discuss the fate of deputy police chief Pol Gen Surachate Hakparn, Prime Minister Srettha Thavisin said on Tuesday.

The meeting will be chaired by the premier today at around 2-3pm.

The commission will meet to consider whether the Royal Thai Police's order to dismiss Pol Gen Surachate, aka "Big Joke", was against the law.

On Monday, Pol Gen Surachate reportedly threatened to file a malfeasance complaint against Mr Srettha if he failed to have the order temporarily dismissing him from the force revoked.

"I believe each individual, including deputy national police chief Pol Gen Kitrat Phanphet, national police chief Pol Gen Torsak Sukvimol and Pol Gen Surachate, all have their own problems and have maturity," Srettha said. "Personal issues must be resolved through legal processes."

Meanwhile, Pol Gen Surachate reportedly filed a defamation lawsuit against a police general who is a member of the Police Commission and a legal expert appointed by the premier.

Surachate also planned to file a defamation lawsuit against another expert and will file another lawsuit against a senior officer next week.
