Public service
Giles Clarke has served with the following public bodies:
In 2010/11, Clarke was elected as Master of the private club the Society of Merchant Venturers in Bristol. The society conducts charitable works, but has been accused of using its present influence to sanitise the memory of Edward Colston.
Cricket
A keen club cricketer, Clarke became chairman of Somerset County Cricket Club, becoming instrumental in developing the club both on and off field and consulting ex cricketers including Sir Ian Botham. He resultantly became a non-executive director of the England and Wales Cricket Board, and as Chairman of Marketing led the negotiations for their new four-year TV and radio broadcasting rights deal signed with BSkyB, Five and the BBC in December 2004.

In April 2015 Clarke was nominated as the ECB's first president, with the intention that president's primary role would be to represent ECB on the International Cricket Council's executive board. Clarke was appointed Commander of the Order of the British Empire in the 2012 New Year Honours for services to cricket.
Private life
Married to Judy, the couple have a son Jack – after whom the brasserie in Bristol is named. A family man and protective of his private life, when his name appeared in the Sunday Times Rich List in the mid-1990s, Clarke took steps to protect his financial interests from the public.
