Abhisit Vejjajiva : Prime Minister of Thailand : Shooting TV Commercial with Sky Exits Films Bangkok Abhisit Vejjajiva — a patrician 44-year-old with an Oxford education — became Thailand's prime minister on Monday amid hopes that he can calm the political storms that have battered the country for the past three years. But untested at the pinnacle of power and said to lack decisiveness, he could face one of the roughest rides in modern Thai history. Abhisit, who heads the former opposition Democrat Party, defeated a loyalist of exiled but still powerful ex-Prime Minister Thaksin Shinawatra in a parliamentary vote. The parliamentary contest came in the wake of mass protests by anti-Thaksin forces that included a weeklong siege of Bangkok's airports.
