Acevo has convened a group of chief executives to campaign for greater voluntary sector involvement in the delivery of public services.
The 12-strong body will be chaired by Counsel and Care chief executive Stephen Burke and will include advisers from the public and private sectors.
Burke said: "I want to make sure the Government recognises the potential of our work, and that its policies translate into concrete reforms. We must turn the vision of a sector 'competing on equal terms' into a reality."
Acevo announced the group in the same week that the NCVO published a report warning against charities and the Government regarding public service delivery by the sector as an end in itself (Third Sector, 4 May).
The group will lobby to ensure the Government implements Acevo's Surer Funding framework on long-term funding, and will campaign to broaden debate about the role of the third sector in carrying out public services.
Other members include Cliff Prior of Rethink, David Harker of Citizens Advice and Clare Tickell of NCH.
The Social Market Foundation is set to publish a book this coming July about voluntary sector involvement in specific areas of public service policy and delivery. It will be written by Acevo.
