The Beijing 2022 Winter Olympics will begin in 4 weeks’ time with more than 2,000 athletes from across the globe expected to take part. Officials have set up a bubble to keep arriving athletes and officials separate from the general population, all part of attempts to prevent coronavirus infections. Some health officials fear the increased transmissibility of the Omicron variant will pose a severe challenge to organisers and athletes can expect to face tougher restrictions compared to last year's summer Olympics in Tokyo. The games are also the subject of a diplomatic boycott by the United States and some of its allies. The White House says it wants to send a clear message that it disapproves of China's human rights record, including its treatment of Uighur Muslims and a crackdown on dissents in Hong Kong. China described the move as an attempt to politicise sport. So what will success look like for the Beijing Olympics? How effective will the Covid protocols be? And how much of an impact will the diplomatic boycott have on the event’s credibility? Paul Henley is joined by a panel of experts. Producers: Junaid Ahmed and Paul Schuster.
