David Cameron banned all contact with the Dalai Lama during crunch talks with the Chinese government over the Euro bailout package earlier this year. The ministers -- Tim Loughton (who was sacked in September) and Norman Lamb -- were barred from attending a lunch with the Dalai Lama in the offices of the House of Commons Speaker John Bercow, minutes before it was due to begin. The pair then wrote to Cameron to protest after the "deeply embarrassing" incident in June this year, according to a copy of the letter obtained by the Channel FourDispatches programme. Loughton told the programme that he and Baker had originally been cleared to meet the Dalai Lama on his visit to the UK. The pair had been given the green light to attend the lunch on June 20 -- Mr Baker is honorarypresident of the Tibet Society and Mr Loughton is a member of the Tibet Society Council. But the then-foreign minister Jeremy Browne intervened, telling moments that they could not attend moments before it was due to begin. The pair wrote a private letter to Mr Cameron in July which they strongly protested about the way they had been muzzled, and complained about the "tremendous pressure put upon each of us at the 11th hour not to attend.
