Pyatongtarn Shinawatra has become Thailand's youngest ever Prime Minister. She succeeded Sretha Thavisin, who was removed from her post by a Constitutional Court ruling.

Bangkok: Thailand's parliament has voted to make Patongtarn Shinawatra the next and youngest prime minister of Thailand, Al Jazeera reported on Thursday.

Petongtarn replaces Sretha Thavisin, who was removed from her post by a Constitutional Court ruling on Wednesday.

Known by the nickname Ung Ing, Petongtarn is the youngest child of billionaire tycoon Thaksin Shinawatra and the third member of the family to hold the country's top job after her father and aunt.

Parliament confirmed the nomination of 37-year-old Pyatongtarn by the ruling coalition of her Pheu Thai party.

Shretha's ouster was the latest chapter in a long-running battle between the military, the pro-monarchy establishment and the populist party that rocked the country's stable politics since he was first elected prime minister in 2001.

He spent several years in exile after being ousted in a military coup in 2006 and returned to Thailand last year on the same day Pheu Thai formed a government.

At a meeting on Thursday night, the ruling coalition chose Petongtarn as a replacement after none of the other 10 parties in the coalition put forward an option.

Thai and its partners hold 314 seats in the parliament, and Patongtarn needs the approval of more than half of the current 493 lawmakers to become prime minister.

Petongtarn helped run the hotel arm of the family's business empire before entering politics three years ago and has never held elected office. She was a constant presence on the campaign trail in the 2023 election when she was one of Pheu Thai's prime ministerial candidates and gave birth just two weeks before polling day.

Earlier, the reformist Move Forward Party (MFP) won the most seats in parliament but was blocked from forming a government by the Senate, which at the time was appointed by the military and had a veto on prime ministerial appointments, Al Jazeera reported.

Last week, the Constitutional Court also voted to dissolve the MFP and ban its executive board members from politics for 10 years as it pledged to reform the draconian royal defamation law.

The party has since been reconstituted as the People's Party.
