1.01pm: This could be significant. Conservative Way Forward, a Thatcherite ginger group within the Conservative party, has issued a statement saying it has "considerable concern" about the state of the coalition talks with Lib Dems. It wants David Cameron to form a minority Conservative government. The full text of the statement is now on ConservativeHome.
Conservative Way Forward probably isn't as influential as it used to be, but it does represent the views of a section of the Conservative party. (Lady Thatcher is its honorary president, and its honorary vice presidents include William Hague, Liam Fox and David Davis.) It wants Cameron to reject a coalition. But, as William Hague explained to journalists last night, the Lib Dems are now insisting on coalition or nothing.
