David Cameron will attempt to paper over the cracks in the coalition over Europe (Chicago Options: ^REURUSD - news) again today at Prime Minister's Questions.
He faces a rough ride in the Commons as Liberal Democrats continue to vent their anger over his EU treaty veto.
Last night the party's MPs (BSE: MPSLTD.BO - news) abstained en masse rather than back a motion congratulating Mr Cameron on protecting British interests.
The snub came after Energy Secretary Chris Huhne accused him of "isolating" the UK and "playing Billy no-mates".
This morning Deputy Prime Minister Nick Clegg will hold talks with business figures and stress his determination to "rebuild bridges" with Europe.
He is then expected to sit alongside Mr Cameron at PMQs - unlike on Monday when he was conspicuously absent from the front bench as the Tory leader made a statement to MPs.
Despite the continuing fallout, Mr Cameron will be encouraged by opinion polls suggesting his hardline stance has gone down well with voters.
Research by YouGov (LSE: YOU.L - news) for The Sun gave the Tories a two-point lead over Labour, on 41% to 39%.
A ComRes/Independent poll found the parties were neck-and-neck on 38%.
Liberal Democrat ministers made their displeasure clear on Tuesday when the Cabinet met for the first time since the controversial veto.
Mr Huhne reportedly complained "proper procedures" for negotiations had not been followed.
He is said to have argued that, as chairman of the Cabinet sub-committee on European Affairs, he should have been consulted during the summit as well as beforehand.
He also apparently broke convention by twice interrupting Mr Cameron as he summed up his talks with fellow EU leaders last week.
At a meeting of Lib Dem MPs last night, Mr Huhne declared "isolation is not a good position" and "playing Billy no-mates is no fun".
Aides of Mr Clegg said he was given a warm reception by his rank-and-file at the two-hour session.
He stressed his determination to "re-engage constructively" with Europe but said it was "essential" to remain in the coalition government.
