In an interview on BBC Radio 4’s Today programme, Cameron said his shadow ministers were leading a review of all quangos that would assess their effectiveness.
He said: “Many of them [will be] slimmed down or reduced, pay levels will be completely different, and some of them will be abolished.”
Quangos are estimated to cost between £34bn and £60bn depending upon how they are defined. Cameron said that 68 quango bosses are earning more than the Prime Minister.
Treasury chief secretary Liam Byrne announced a detailed review of quangos at the weekend and claimed that the Tories’ policy proposals included creating around 17 further quangos.
Cameron rejected this accusation.
