The Dalai Lama has arrived in Britain for an 11-day visit.The Tibetan spiritual leader will attend Parliament to give evidence on human rights to MPs on the Foreign Affairs Committee.But a decision not to welcome him to 10 Downing Street has sparked anger among supporters.Instead of the political setting called for by many politicians and Tibet campaigners, Prime Minister Gordon Brown will meet the Dalai Lama at Lambeth Palace, home of the Archbishop of Canterbury, on Friday.Downing Street has described it as an "inter-faith meeting with several other religious leaders".Former Liberal Democrat leader Sir Menzies Campbell said: "Treating the Dalai Lama as only a religious leader simply ignores reality. "There is no reason why he should not be received at No 10 Downing Street."He added: "Many people will conclude that the Prime Minister is trying to have it both ways, to see him and not offend the Chinese government. The Prime Minister is entitled to see who he wants."The Dalai Lama will receive an honorary degree from London Metropolitan University later.He will give a speech at the event, in central London, and will meet Tibetan students.The Dalai Lama is also set to give five days of teachings from Saturday at Nottingham Arena.Scotland Yard said "appropriate" policing would be in place and that it was aware of at least two planned protests when the Dalai Lama is due to visit Parliament on Thursday.
