Seventy per cent of local enterprise partnerships, the bodies set up to help businesses and local councils work together, have no plans to appoint voluntary sector representatives to their boards, according to the Association of Chief Executives of Voluntary Organisations.
Stephen Bubb, chief executive of Acevo, has written to the decentralisation minister Greg Clark claiming LEPs have not listened to the government's message that the sector should be involved.
"Not all LEPs have taken this message to heart, with 70 per cent of approved LEPs having no plans for voluntary sector representations on their board," the letter says.
It asks Clark to urge LEPs to appoint voluntary sector representatives.
"If the voluntary sector is to take on greater responsibility for driving economic and social innovation as part of the government's commitment to devolving power to local communities and building the big society, then it is vital that the voluntary sector has a voice in shaping the strategic priorities of the local economy," the letter says.
The Communities and Local Government department was unable to comment.
