Federer wins 2017 bbc personality award fourth time
I think there may be some confusion here!
Roger Federer is a professional tennis player, not a personality who would be eligible for a BBC Personality Award. The BBC Personality Award is a British television award that recognizes outstanding contributions to the world of entertainment, sports, and other fields.
In 2017, the BBC Personality Award was won by Mo Farah, a British distance runner, not Roger Federer. This was Farah's second time winning the award, having also won it in 2013.
Federer has won numerous awards and accolades throughout his tennis career, including 20 Grand Slam titles, but not a BBC Personality Award.
