Novak Djokovic can defend his Wimbledon title after organisers said players who are not vaccinated against Covid-19 will be allowed to compete.
The Serbian world number one, 34, was not allowed to play at the Australian Open in January following a row that centred around him being unvaccinated.
"The requirement set out by the government to enter the UK does not include mandatory vaccination," All England Lawn Tennis Club chief executive Sally Bolton told a news conference.
"Therefore, while it is of course encouraged, it is not a condition of entry."
Wimbledon takes place from 27 June to 10 July.
