The general election process will begin next year as planned, probably no later than December, Prime Minister Prayut Chan-o-cha said for the first time after voters approved the draft charter in Sunday's referendum.
According to Section 260 of the draft constitution, the election of MPs and the appointment of senators shall be completed within 150 days after all 10 organic laws take effect.
The prime minister made the assurance on Tuesday before attending a meeting of the cabinet and the National Council for Peace and Order (NCPO) at Government House.
The meeting discussed the unofficial results of the charter referendum and preparations for the general election.
Gen Prayut did not comment on the referendum result but said the poll process would happen in 2017 as planned.
"Please have confidence in the roadmap. I've never said otherwise," the prime minister said.
NCPO spokesman Winthai Suvaree said after the meeting Gen Prayut told the meeting authorities would continue to explain the contents of the draft charter to the public and also inform them of the steps to be taken after the constitutional referendum.
Meechai Ruchupan, an NCPO member and head of the Constitution Drafting Committee, said before the meeting the draft charter could be ready for submission for royal approval in either October or November and work on the 10 organic laws would start with four election-related laws.
They are the laws governing elections, senators, political parties and the Election Commission.
He said his committee would work as fast as possible and the election process should begin next year.
Asked if election-related laws would result in changes to political party registration, Mr Meechai said he had not considered the point.
Mr Meechai earlier said the constitution writers would need 30 days to amend the draft to allow senators to jointly vote with MPs on the next prime minister as approved by voters in the referendum. After that, the Constitution Court will take 30 days to vet the draft before sending it to the prime minister to seek royal approval within 30 days.
