Thailand's parliament has chosen business tycoon Anutin Charnvirakul as the country's prime minister - the third in two years, after yet another leader was removed from office.

Paetongtarn Shinawatra, who belongs to Thailand's most powerful political dynasty, was removed by the constitutional court last week for ethical violations over her handling of the border dispute with Cambodia.

Anutin's Bhumjaithai party broke from the coalition led by the Shinawatras' Pheu Thai, and secured enough support in parliament to win the premiership.

The uncertainty may not be over for Thailand, which has seen multiple administrations deposed by court interventions and military coups in recent years.

Anutin's rise to the premiership deals a significant blow to the Shinawatra family, which has dominated Thai politics since 2001, when Paetongtarn's father, Thaksin, became PM.

Paetongtarn was the fifth Thai prime minister to be dismissed by the Constitutional Court, all from administrations backed by her father Thaksin.

Now, Anutin finds himself at the helm of a government that faces immense pressure from differing political ideologies, as his coalition, while powerful, is expected to remain precarious.

His administration starts with commitments to amend the constitution and hold elections within four months, a challenge that could redefine Thailand's political landscape once again.
