Lawmakers in Thailand are still struggling to select the country's next prime minister, more than two months after the May general election.

The parliament has announced that it will hold another session on August 4.

People in the nation are wondering whether the second round of voting to elect a new prime minister will be held next week.

The second round was initially scheduled to take place on July 19. The leader of the progressive Move Forward Party wanted to run again as a candidate.

But conservative lawmakers blocked Pita Limjaroenrat from doing so, by passing a motion. They claimed his re-nomination would breach a parliamentary regulation.

An Ombudsman said parliament's rejection of Pita's re-nomination was unconstitutional. On Monday, the Ombudsman asked the Constitutional Court to issue a ruling on the matter.

The court is expected to make a decision before next week's parliamentary session. If it disagrees with the Ombudsman, the prime ministerial vote will be held on the following Friday.

Eight opposition parties are trying to form a coalition. They have said that they plan to field a candidate from the Pheu Thai Party. That party is affiliated with former Prime Minister Thaksin Shinawatra.

Conservative lawmakers say they will not vote for a Pheu Thai Party candidate, if Pita's party is a member of the coalition.

The Pheu Thai Party is currently holding talks with conservative parties. Many observers believe it is trying to form a coalition without the Move Forward Party.
