Ubon Ratchathani _ The lone winning Mahachon candidate was undecided yesterday about his future as the party looked to be on the verge of dissolution.

Toon Jintavej, who defeated former MP Chatri Piriyakijpaiboon of Thai Rak Thai in constituency 11 of Ubon Ratchathani, said if his party merged with Chart Thai, he would then decide if he should stay or move on to join another party.

He said he would base his decision on the advice of voters who backed him in Sunday's general election.

Key members of Mahachon are widely expected to dissolve their party following the embarrassing election outcome.

Before Sunday's poll, Mr Toon was a five-time MP for Ubon Ratchathani representing the Social Action, Puang Chon Chao Thai, New Aspiration and Chart Thai parties in separate elections.

In the 2001 election, Mr Toon lost to Mr Chatri when he was with Chart Thai.

He defected to Mahachon for this election as he was at loggerheads with Chart Thai leader Banharn Silpa-archa.
