The protesters under the People’s Democratic Reform Committee (PDRA), led by Supaphol Iammethawee, secretary-general of PDRC Nakhon Ratchasima, marched to the municipality office which is a polling station at around 10.30am Sunday.
On the way, they encountered around 200 supporters of the United Front for Democracy against Dictatorship (UDD) who had gathered near the polling station.
Both sides had trucks and loud speakers and began a verbal attack on the other. The PDRC moved 50 guards to the front of their group. Later, around 150 police officers from the Protection and Crowd Control Division moved in to calm the situation.
The PDRC group took around 15 minutes to walk past the UDD supporters who at both sides of the road.
Mr Supaphol tried to negotiate with the director of the election for constituency 1 to call off the advance voting but there was no conclusion, so the PDRC resolved to carry on the gathering at the poll unit until 3pm.
