Richard Ackroyd: 25% of bonus going to charity.
The chief executive of Scottish Water, one of Scotland highest-paid public servants, says that he will donate a quarter of his bonus to charity.
Richard Ackroyd, whose basic salary is £263,000, said the money will go to WaterAid, which improves access to safe drinking supplies around the world.
The amount to be given will depend on the size of the bonus, which will be finalised in June. In 2008-9 his bonus was £100,571, just under the permitted 40% maximum.
Mr Ackroyd said: "I have looked carefully at all the circumstances and at how people are being affected by the consequences of the downturn in the economy.
"My priority as chief executive is to ensure that Scottish Water continues to deliver increasing value-for-money for our customers and that objective is even more vital in the current circumstances."
Mr Ackroyd ranks at the bottom of six UK water companies for chief executives' potential annual earnings including maximum bonuses.
Last year finance secretary John Swinney wrote to public sector chiefs urging them to give up their bonuses. The 28 public bodies and government agencies he wrote to included Scottish Water, Scottish Enterprise and the Scottish Environment Protection Agency.
A Scottish Government spokeswoman said: "This is a welcome step by Mr Ackroyd.
"The Finance Secretary has made clear his desire that chief executives of public bodies should give up some or all of their bonus voluntarily.
"That request has already produced positive responses."
