Wimbledon bosses are consulting the government about whether to allow players from Russia and Belarus to compete in this year’s tournament.
The All-England Lawn Tennis Club said the issue is “complex and challenging”.
Belarusian and Russian players, such as men’s world number two Daniil Medvedev, have been allowed to play on tour, but not under their countries’ flags.
Russia has been banned from defending its Davis Cup and Billie Jean King Cup team titles after the country’s invasion of Ukraine – a military operation supported by Belarus.
Teams and athletes from both countries have been subject to a variety of suspensions and sanctions from a number of bodies across the sporting spectrum.
Wimbledon will be held from 27 June to 10 July.
