Progressive Movement chairman Thanathorn Juangroongruangkit was conspicuous by his absence from the political scene until recent controversies erupted over his vaccination record and a work of art.
The Palang Pracharath Party's (PPRP) failure to capture two House seats in Sunday's by-elections in Chumphon and Songkhla has prompted questions over whether the ruling party, which only just recently made inroads with voters in the South, is on the way out of government.
The Democrat Party looks set to retain House seats in both Chumphon's constituency 1 and Songkhla's constituency 6 after its candidates emerged winners in unofficial results from Sunday's two by-elections.
The Kla Party will field candidates in all upcoming by-elections, seeing the contests as an opportunity to reach out to voters ahead of the general election, even if its chances of winning are slim.
