The three are contained in a list of 177 organisations to be scrapped as part of the coalition government’s proposed bonfire of the quangos.
Cabinet Secretary Sir Gus O’Donnell this morning called for an immediate investigation into the leak. A Cabinet Office spokesman said: "We deeply regret any extra uncertainty for employees that this irresponsible leak has caused."
The Commission for the Compact, which was established in 2007, was allocated £5.6m between 2008 and 2011 in the last comprehensive spending review and employs 15 staff.
Richard Corden, its chief executive, said he was unable to discuss the list, which was published in The Daily Telegraph. "I can’t comment on leaks," he said.
The commission shares Birmingham offices with Capacitybuilders, which was set up in 2006 to oversee the previous government’s £231m ChangeUp programme, designed to strengthen the voluntary sector’s infrastructure.
Capacitybuilders, which received a £39.3m government grant in 2009/10, employs 49 staff. Its chief executive, Matt Leach, announced his departure earlier this month.
"Capacitybuilders will not comment on leaked information," said a spokeswoman for the organisation.
The Office for the Civil Society Advisory Body, previously known as the Office of the Third Sector Advisory Body, replaced three separate advisory bodies when it was formed in 2008 to advise ministers on what charities want.
Its chair, Baroness Jill Pitkeathley, is paid £12,500 a year and its 11 other members receive £250 a day for about 15 days a year.
