Olympic venues in Tokyo will not be able to admit spectators for this summer's Games after the coronavirus pandemic forced the declaration of a new state of emergency in the Japanese capital, Tokyo 2020 organising committee president Seiko Hashimoto has said.

Organisers had hoped that Japanese residents would be able to attend the Games, and last month announced that venues could be 50 per cent full, up to a maximum of 10,000 people.

However, a rise in coronavirus infections has forced the Japanese government to reimpose more stringent measures from Monday until August 22, and organisers confirmed on Thursday that Games venues in the Tokyo prefecture would now not be allowed to admit spectators.

In venues located in areas where emergency measures are not in force, organisers said that the relevant local authorities would decide on spectator levels.

A decision on whether spectators for the Paralympic Games would be taken on July 16, a statement from the organisers said.

The statement concluded: "All five parties deeply regret for the athletes and for the spectators that this measure had to be put in place."
