Roger Federer put Kate Middleton in an awkward situation at Wimbledon after breaking Royal protocol.
The recently-retired tennis great made a surprise appearance at the annual tennis tournament on Tuesday and was invited to sit in the Royal Box to watch Elena Rybakina take on Shelby Rogers on centre court.
But when entering the box, he broke a huge piece of Royal protocol by touching Middleton on the back while saying hello, reports The Daily Star.
