The Democrat Party has denied it has been approached by the regime to join the next coalition government in exchange for "A-list" ministries.

Democrat leader Abhisit Vejjajiva on Tuesday dismissed as untrue information from a political source that his party was given an offer to join the next government and rewarded with ministerial posts in top-grade ministries.

The information is believed to have come from a source in the pro-regime Palang Pracharath Party (PPRP).

Mr Abhisit made his remark under the assumption that the PPRP will become the core party that manages to consolidate enough allies to form the next government.

Deputy Prime Minister Prawit Wongsuwon, meanwhile, also denied the regime has extended an early invitation to the Democrat Party to join the proposed government coalition through the party's former secretary-general Chalermchai Sri-on. Mr Abhisit said talk is growing that the PPRP, the Democrats and Pheu Thai will emerge as the largest parties after the next election.

He insisted the PPRP has claimed it will win more than 350 seats. If that assertion comes true, it would not need the Democrats to join it in government.

There are 500 seats at stake in the House of Representatives and a party or a coalition needs to garner more than 250 to command a House majority.

"If [the current government] manages the affairs of state this way, it will be hard to work together. The people are in dire straits," Mr Abhisit said.

The Democrat Party is expected to announce its candidates who will stand in the Feb 24 election at the end of the month.
