The Big Society Network, launched as part of a flagship scheme by David Cameron in 2010, is reportedly being investigated over the misuse of government funds.
It is said the organisation was given at least £2.5 million of National Lottery funding and public-sector grants - but is now under scrutiny by the Charity Commission, reports the Independent.
There are also claims that government grant-awarding bodies were pressured into handing over cash to the organisation.
