Srettha Thavisin, until recently chief of one of Thailand¡¯s biggest real estate developers, was on Tuesday voted in as prime minister at the head of an unlikely alliance of populists and pro-military parties after weeks of post-election deadlock.

Srettha, 61, won a vote in parliament to become premier hours after the founder of his populist Pheu Thai party, Thaksin Shinawatra, made a dramatic return to Thailand after 15 years of self-exile and was taken straight to jail.

¡°It is an honor to be elected prime minister,¡± Srettha told reporters after the vote. ¡°I would like to thank all the Thai people.
