The Foreign Office appears to be insisting that any programme it organises must include meetings with Tibet human rights lobby groups and a group of parliamentarians who support the Dalai Lama.
"We do have concerns about human rights in Tibet," said a Foreign Office spokesman. "So we would see this as an opportunity for us to express our concern directly to Raidi."
Raidi - he just has this one name - is the deputy Communist Party secretary in Tibet, and the highest ranking Tibetan within the Chinese-run system. He will head the seven-person delegation to Britain, all but two of whom are ethnic Tibetans.
The visit, from 3-5 December, will be the first official delegation from inside Tibet since 1948. Two years later, China invaded Tibet, eventually forcing the Dalai Lama to flee in 1959.
