BANGKOK, 7 March 2011 (NNT) – The opposition Pheu Thai Party has asked the British government to investigate if Prime Minister Abhisit Vejjajiva has ever used any rights as a British citizen or not.

The request was contained in a letter submitted to British Prime Minister David Cameron on Monday by Pheu Thai Party Spokesperson Prompong Nopparit via the British embassy in Bangkok. Speaking upon his submission of the letter, Mr Prompong said his move was to find out whether Prime Minister Abhisit was trying to conceal his dual citizenship in order to protect his Thai premiership.

According to the letter, the British government is requested to answer if Prime Minister Abhisit has ever entered the UK without a visa, if the PM has ever claimed British nationality for studies at Eton College and at Oxford University, and if he had ever used any rights as a British citizen.
