Foreign Secretary William Hague has signalled that the group of Tory backbenchers' ideas on Europe chime with the thinking at the top of the Conservative Party.
Mr Hague hailed the Fresh Start Project's Manifesto for Change in a foreword as a "well-researched and well-considered document full of powerful ideas for Britain's future in Europe".
"Many of the proposals are already Government policy, some could well become future Government or Conservative Party policy and some may require further thought," he said.
Mr Hague described the document as "essential reading" for those drawing up the Tory manifesto for the 2015 general election.
Centrica's boss warns an EU referendum risks "total destabilisation" for businesses; the Next chief suggests that view is "scaremongering."
There will be sympathy, yes. But will they agree with him? No.
Conservative MPs said their "achievable" proposals to change Britain's role in Europe do not represent an ultimatum to the Prime Minister.
