London 2012 silver medallist Rob Williams retires

Olympic rowing medallist Rob Williams is quitting the sport to continue his career in banking.

Former world champion Williams won silver at London 2012 in the lightweight men's four, with Richard and Peter Chambers and Chris Bartley.

The quartet missed out on gold to South Africa by a quarter of a second in a thrilling finish at Eton Dorney.

Williams said: "Ultimately I feel very fortunate to have had such an enjoyable career."

The 28-year-old joined banking firm Goldman Sachs as a trader following the London games.

In a successful international career which spanned seven years, Williams also won a World Championship title in New Zealand in 2010.

Williams, from Maidenhead, also completed a PhD in X-ray crystallography in 2012.

Sir David Tanner, the performance director of GB Rowing, said: "Rob converted his significant talent in our sport to great effect. He will be a great asset to his employers and we wish him well with the future."
