Olympics in numbers: which countries are the best at Summer Olympic sports - from athletics to volleyball
and live on Freeview channel 276
Tokyo is bracing for an opening ceremony like no other at the Olympic Stadium on 23 July, with the athletes’ parade and traditional lighting of the torch taking place in front of empty stands.
A British delegation of just 22, including flag bearers Hannah Mills and Mohamed Sbihi, will march at the opening ceremony for the Tokyo Olympics.
Athletes from canoe slalom, fencing, weightlifting, sailing, boxing, rowing and trampolining will feature in the curtain-raiser, which is being held behind closed doors at the purpose-built Olympic Stadium.
A ring of steel has been erected around the stadium, meaning the excited locals, who had been due to be a part of the ceremony until the decision to ban spectators from the Games was made earlier this month, were left to watch those lucky enough to be allowed in from behind fences.
Japan Standard Time (JST) is eight hours ahead of British Summer Time (BST), meaning the ceremony started from 12 noon for UK viewers - with sporting competitions already taking place.
Yet despite the games being postponed for the first ever time in Olympic history because of Covid, the level of competition among countries and athletes remains as high as ever.
These are the top countries which are the best at each Summer Olympic sport - from athletics to volleyball.
