The government coalition is planning to submit draft amendments next week to two organic laws to reflect constitutional changes in the election system, according to Chinnaworn Boonyakiat, Democrat MP for Nakhon Si Thammarat.
Mr Chinnaworn, who is also deputy chief government whip, said the bills -- one involving the election of MPs and another on political parties -- deal particularly with the reinstatement of the two-ballot system.
He also said the government coalition is expected to vote for a draft amendment sponsored by the cabinet despite some disagreements, noting such differences will be sorted during the draft's scrutiny process.
The cabinet is expected to use the draft prepared by the Election Commission.
Mr Chinnaworn said the government's working panel on the drafts has been invited by Deputy Prime Minister Wissanu Krea-ngam to discuss the bills on Monday.
Meanwhile, the main opposition Pheu Thai Party yesterday submitted its draft amendments on both organic laws to House Speaker Chuan Leekpai via Sukij Atthopakorn, an adviser to Mr Chuan.
Party leader Cholnan Srikaew said the drafts seek to change the calculation and distribution of party-list MPs and the primary voting system, but these proposed revisions are in line with the charter.
He said the calculation method of party-list seats is straightforward when compared with the one used in the 2019 general election, even though there will be more than one round of calculation involved.
As for the primary voting, he said the party's draft does not seek to scrap primary voting, which is required under the charter's Section 45.
The proposed change is aimed at cutting steps involved in the candidature process and making it easier for political parties to field constituency candidates, he said.
