The House of Commons is to be given a chance to vote to declare that a genocide is under way in Xinjiang province in China, in a move likely to damage Sino-British relations.

The organisers hope that at least two-thirds of MPs will vote on 22 April to back the all-party motion in a declaration of intent against China for its treatment of the Uyghur Muslims.

Relations are already at a low ebb after China sanctioned 10 individuals and entities in the UK in response to the Foreign Office imposing sanctions on four Chinese officials implicated in setting up detention camps in Xinjiang.
