Thailand’s top pro-democracy groups moved to begin talks on forming a government after a stronger-than-forecast showing in Sunday’s elections, with the head of the Move Forward Party claiming a mandate to serve as the nation’s next prime minister.

Pita Limjaroenrat took to Twitter in the early Monday morning to say he would be a prime minister for all, later adding that he’s reached out to five parties for support. With Move Forward leading in both total seats and popular votes, he won public backing from the Pheu Thai party that finished in second.

"Today I’m ready to be Thailand’s 30th prime minister,” the Harvard-educated Pita, 42, wrote. "We have the same dreams and hopes and we believe that our beloved Thailand can be better.”
