Conservative former leader Sir Iain Duncan Smith begged Johnson to ensure the UK follows the lead of the United States by having a full diplomatic boycott of the Games in February.

Johnson said the government has "no hesitation" in raising concerns over human rights abuses with China, adding in the Commons: "There will be effectively a diplomatic boycott of the Winter Olympics in Beijing.

"No ministers are expected to attend and no officials. What I can tell the House is I don't think sporting boycotts are sensible and that remains the policy of the government."

Both the US and Australia have announced diplomatic boycotts over Beijing's record on human rights, particularly the treatment of the Uighur Muslim community in Xinjiang province.

The Princess Royal, who is president of the British Olympic Association and a member of the International Olympic Committee, is meeting with the IOC on Thursday to discuss timings ahead of the opening ceremony.

Anne will be considering the options for travelling to the IOC meetings and games, a source said.

Sir Iain welcomed the prime minister's announcement and said he hoped "many other countries will follow suit".

Australian Prime Minister Scott Morrison announced a boycott because it is "the right thing to do".

In Australia's case, it was not only human rights concerns but also a series of political disputes with China which had triggered the move - including the AUKUS pact with the UK and US over nuclear-powered submarines.

He said his government was very happy to talk to China about their differences "but the Chinese government has consistently not accepted those opportunities for us to meet".
