Each of the 11 groups will nominate 50 candidates while 76 other representatives will be chosen from 76 provinces, and then the 626 people will vote among themselves to fill the 250 seats in the council, Prayuth Chan-ocha said in his weekly televised address.

The voting has to comply with the condition that the 11 groups will be represented in the council, the chief of the National Council for Peace and Order (NCPO) stressed.

Prayuth also said an interim charter that was expected to be promulgated this month would have 50 articles.

The charter will balance the power of the NCPO and an interim government that will take shape in September, he said.

The NCPO will stay on to handle security affairs while the government will be in charge of administering the country, he said.

Prayuth added the provisional charter would have certain restrictions for the purpose of solving the country's problems, but did not elaborate.
