The government is to unveil plans for a “bonfire of quangos”, with up to 180 organisations expected to be abolished.
Ministers say this is needed to sort out the “proliferation and mess” caused by the previous Labour administration.
Leaked documents suggest Cycling England and the Advisory Committee on Organic Standards could be among those axed.
The government has already announced several quangos, including the UK Film Council and Audit Commission, will go.
The Health Protection Agency is another high-profile body whose demise will be confirmed by the Cabinet Office in a statement at about 0930 BST.
Quangos – “quasi-autonomus non-governmental organisations” – are arm’s length bodies funded by Whitehall departments but not run by them.
Opponents argue that they decrease ministers’ accountability and increase waste.
But unions say many of the coalition’s planned changes will damage public services, cost jobs and not result in government savings, as the expenses involved in abolishing quangos will be large.
The government is expected to publish a list showing there are more than 700 quangos, adding that the number and costs have risen under Labour.
But Conservative MP Douglas Carswell told the BBC that “cowardice” of politicians of all parties had contributed to the growth and that Parliament, rather than the government, should be in charge of monitoring the situation.
