Astrid Bonfield, the chief executive of the Queen Elizabeth Diamond Jubilee Trust, and Tony Burton, former director of policy and communications at the Design Council, have been appointed to the board of the Big Lottery Fund.
The appointments were announced in a Cabinet Office statement on Friday and are for up to four years, with the option of reappointment for a second term.
Bonfield is also chief executive of the Diana, Princess of Wales Memorial Fund and is a former director of policy at the Aga Khan Foundation.
Burton was founder director of Civic Voice, which promotes the civic movement.
They replace Diana Whitworth, John Gartside and Roland Doven, who have all served two four-year terms. As a result, the BLF board will reduce from 10 people to nine.
The new board members will each be paid £7,848 a year for approximately three days a month and start on 1 December.
Francis Maude, the Minister for the Cabinet Office, said: "Astrid Bonfield and Tony Burton will bring invaluable new expertise to the board of the Big Lottery Fund, where they can make an important contribution to its vital work."
