The outgoing chief executive of the Financial Services Authority has donated his £143,750 bonus to a charity supported by the Duchess of Cambridge.
Hector Sants has handed over his windfall to the Oxford-based group The Art Room under the Workplace Giving UK scheme, the charity said.
Founder director Juli Beattie said: "We are thrilled that Hector Sants has asked the FSA to donate his bonus to The Art Room.
"With this generous gesture we will be able to offer many more children the support they need to achieve their potential in education and make more positive choices for themselves in their young lives."
The Art Room was set up in Oxford in 2002 to offer art therapy to children and young people aged between five and 16.
In January 2012 it was announced that Kate would become the charity's royal patron.
Mr Sants' wife, Caroline, worked as volunteer with The Art Room for three years and the couple's sons, Arthur and Hector, have raised more than £20,000 to date, while a third son, Edward, is planning to run the 2013 London Marathon in support of the group.
