New Delhi: Swiss tennis maestro and 20-time Grand Slam champion Roger Federer and his wife Mirka on Wednesday joined the global sporting community in the battle against coronavirus pandemic as he and his wife Mirka donated 1 million Swiss Francs for the most affected families in Switzerland.

Federer said in an Instagram post that the donation is being made towards the "most vulnerable families" in Switzerland.

"These are challenging times for everyone and nobody should be left behind. Mirka and I have personally decided to donate one million Swiss Francs for the most vulnerable families in Switzerland," said Federer in the post.

"Our contribution is just a start. We hope that others might join in supporting more families in need. Together we can overcome this crisis! Stay healthy!"
