Andy Murray is "not supportive" of players from Russia and Belarus being banned from Wimbledon but says there is no "right answer" on the issue.
Players from the two countries cannot play at this year's Grand Slam because of Russia's invasion of Ukraine.
The All England Lawn Tennis Club (AELTC) has also banned Russian and Belarusian players from all other UK grass-court tournaments.
Meanwhile, Rafael Nadal called the ban "very unfair".
Belarusian players were included in the ban because the country has supported Russia's military action in Ukraine.
In March, the UK government is understood to have asked national governing bodies to request written confirmation from Russian and Belarusian players of their neutrality if they wanted to compete in events in England.
