This announcement came after Pheu Thai was appointed by the coalition to seek more votes to ensure that forming a government would run smoothly.
Pheu Thai Party leader Cholnan Srikaew said the party had held discussions with many political parties to hear their ideas on forming a government comprised of the eight-party coalition.
He said Pheu Thai will seek comments from the Senate, adding that the party has prepared its representatives for the talk.
The eight-party coalition will consider issues from these discussions on Tuesday at 2pm, he said, adding that a press conference would be called after the meeting.
The eight-party coalition is made up of Move Forward, Pheu Thai, Thai Sang Thai, Thai Liberal, Prachachart, Fair, Plung Sungkom Mai, and Peu Thai Ruamphalang parties.
