Ed Miliband should hold his nerve and resist demands to make his own hasty referendum pledge.
Miliband is making a strategic mistake by aligning the party with an EU political elite intent on exerting control over all 27 members states, regardless of the wishes of each electorate.
After Gove and Hammond's interventions, the Prime Minister will find it harder to sit on the fence at his press conference with Obama today.
Labour for a Referendum, which has the support of 15 MPs, aims to force Miliband to commit to holding an in/out EU referendum after the next election.
As it was for the "Tartan Tories", the real test for UKIP is not whether it can take votes off the Conservatives but whether it can build a broader long-term coalition.
Were the EU referendum amendment passed, Cameron would either have to resign or abandon centuries of parliamentary convention.
Contrary to Nigel Lawson, the EU is not a monstrous bureaucracy, but the policy mix of austerity and reform is failing.
UKIP is the British version of a Europe-wide rejection of mainstream, established politics.
If, as Lawson predicts, Cameron's renegotiation strategy fails, the Tory party will suffer its worst split since the reform of the Corn Laws.
MPs just want Cameron to prove he means business (and that the Lib Dems don't).
