The Move Forward Party (MFP) and the Pheu Thai Party have agreed to have Prachachat Party leader Wan Muhammad Nor Matha as the House Speaker, while MFP and Pheu Thai will each have one deputy's seat.

MFP leader Pita Limjaroenrat said on Monday night that both parties agreed on Mr Wan Muhammad Nor to be chosen as the House Speaker on Tuesday. MFP would have the first deputy House Speaker's seat and Pheu Thai the second.

He said that the six other coalition allies supported the decision. Prachachat is among the allies.

"This agreement is for unity among the eight political parties, who will do their best to nominate me as the prime minister," Mr Pita said.

He said the eight coalition allies would support him as their sole prime ministerial candidate.

Pheu Thai deputy leader Phumtham Wechayachai said he proposed Mr Wan Muhammad Nor as the House Speaker because the Prachachat leader was neutral and the proposal was a means for coalition allies to proceed with their government formation.
