Labour leader Ed Miliband has appealed to disenchanted Liberal Democrats to work with him against the coalition Government.
He called on Lib Dems concerned that their party's alliance with the Tories was shifting Britain "to the Right" to submit ideas to Labour's policy review.
Shadow minister Liam Byrne would be working with former Lib Dem policy director Richard Grayson on the project.
He identified the economy, electoral reform and issues surrounding social mobility as areas in which many Lib Dems shared similar interests to those of Labour or even the same interests.
"To those who are reluctant to abandon ship but are concerned about the direction of their party, I invite them to work with us on issues of common interest," he said at a Westminster press conference.
Labour's policy review would be asking for ideas from outside the party who "share our values, specifically from the Liberal Democrats".
"I look forward to hearing what they have to say and working with them."
