Quadfather Peter Norfolk retires from wheelchair tennis

Peter Norfolk, the 2004 and 2008 Paralympic champion, is quitting full-time wheelchair tennis.

Norfolk, known as the Quadfather, was the British team's flag-bearer at the opening ceremony of London 2012.

He said: "I haven't had a break from the Tour for 12 years and I feel it is time to dedicate some time to other areas of my life. I have enjoyed some incredible moments and I want to thank everyone who has helped me get to the top."
