Chris Pond has resigned as chair of non-departmental public body Capacitybuilders and been replaced on an interim basis by Stephen Dunmore.
Pond, who has held the post since 2006 and was due to step down in 2011, announced his departure today. He was paid £18,000 a year for the 60-days a year position, but said he needed to devote more time to his role as director of financial capability at the Financial Services Authority.
Dunmore, who was chief executive of the Big Lottery Fund from 2004 to 2008, had been a board member at Capacitybuilders since August last year.
A Cabinet Office spokesman said the search for a permanent chair would not start until next year, so Capacitybuilders, which manages the Government's ChangeUp programme to strengthen the voluntary sector's infrastructure, could focus on delivery.
During his tenure as interim chair, Dunmore will step aside from his position on the Office of the Third Sector advisory body, for which he is paid £250 a day for 15 days a year.
"I look forward to working with the Capacitybuilders staff and board and the sector as a whole, at a time when the ability to access high-quality support and advice is more important than ever to those working in the third sector," said Dunmore, who also chairs the BBC's charity appeals advisory committee and the charity National Family Mediation. He has declared no political activity.
Third sector minister Angela Smith said she was grateful to Pond for his hard work and dedication.
"I want to maintain consistency and stability for Capacitybuilders, which is why I've appointed Stephen Dunmore as the interim chair," she said.
