Comedian Francesca Martinez has refused to carry the Olympic torch in protest at China’s human rights abuses.
The stand-up, who has celebral palsy, was invited to carry the flame through London this weekend as part of the build-up to the Beijing games.
But she has now dropped out, because of China's treatment of Tibet.
Martinez – who has appeared in Grange Hill and Extras - told ITN: ‘I was very honoured to be asked, and very honoured to represent the disabled community.
‘I fully support the Tibetan cause and in a way I feel that, because of the mounting pressure and the ongoing violence in Tibet, that torch-bearers should turn down their role.’
Hundreds of protesters are expected to line the route when the torch passes through the capital on Sunday.
Britain's number one badminton player Richard Vaughan has also refused to take part in the relay, but the 80 torch bearers will include former Blue Peter presenter Konnie Huq and Olympic gold medallists Dame Kelly Holmes, Tessa Sanderson and Duncan Goodhew.
