There is a strong possibility that Bangkok governor Aswin Kwanmuang will seek to return to office and compete in the election later this year, according to the Rak Krung Thep group.
The group, which supports the incumbent, said the Bangkok governor and Pattaya city mayor elections were approved by the cabinet last week.
The elections are likely to take place in May. The Election Commission (EC), which has the authority to set election dates, will meet tomorrow to discuss organising the polls.
