Government spokesman Lt-General Sansern Kaewkamnerd denied knowing anything about the removal of the 1932 Siamese Revolution peg.

He also refused to comment about the issue during a telephone interview with The Nation on Saturday.

A Facebook page called Mhud Khana Ratsadorn alerted the public on Friday that the historical brass peg had been replaced with a new one with different wording that says nothing about the 1932 revolution.

The revolution changed the country’s ruling system from absolute monarchy to constitutional monarchy.

The government’s main communication means with the press – the chat room in the LINE application – was still active but there was no explanation about the incident.

At noon on Saturday, it just sent a message regarding Thailand being ranked by the United Nations as one of the happiest countries.
