The sister of ousted prime minister Thaksin Shinawatra today announced an agreement to form a five-party coalition government after her Pheu Thai Party won a landslide victory in Thailand’s parliamentary elections.

Thailand's prime minister Abhisit Vejjajiva has resigned as leader of the outgoing ruling party after its resounding defeat by the party considered a proxy for ousted former leader Thaksin Shinawatra.

THAILAND’S election body called for the dissolution of the ruling party, piling the pressure on embattled Prime Minister Abhisit Vejjajiva after the bloodiest political unrest in 18 years.
