Thailand's Pheu Thai party will nominate Chaikasem Nitisiri as its prime ministerial candidate, following the dismissal of Paetongtarn Shinawatra by a court order, a party official said on Friday.

Chaikasem, 77, is a lawyer and former attorney general with a long legal career in the bureaucracy before becoming justice minister in 2013.

The news comes as leaders of the Bhumjaithai party said they would hold talks with the opposition People's Party, the largest force in parliament.

Bhumjaithai's leader Anutin Charnvirakul is among five candidates eligible to become prime minister.

The Bhumjaithai party in June quit Paetongtarn's coalition, in which it was the second-largest party, over Paetongtarn's phone conversation with Cambodia's former leader Hun Sen that led to her dismissal by the Constitutional Court.

After the dismissal, Paetongtarn said she had sought to safeguard the country's interests in the phone conversation.

"The verdict today caused a change in Thai politics, we all have to help, all sides, whether government or opposition, or the people, all of us have to work together to build political stability and to ensure that there won't be another turning point again," she said. (Reuters)
