It is expected that a high number of Yingluck’s supporters will show up at the Supreme Court on the day in a show of moral support.

Police have said they are assessing the situation.

Chalermchai said Prime Minister Prayut Chan-o-cha has not instructed concerned authorities to come up with special measures, although the situation is still being assessed.

However he said police will have the prime security role.

Chalermchai said police are obliged to probe any alleged irregular activities concerning the issue including the mass transport of Yingluck supporters via vans when she gave her closing statement in the case on August 1.

Any politically motivated or seditious acts are prohibited, and intelligence officers are looking into the matter, he said.
