Shaken by a slump in the polls and tarred by accusations of running an 'omnishambles' administration, the coalition partners have pledged to focus less on their differences and more on what binds them together. This phase of 'proalition' is designed to minimise trouble, yet the coming weeks present the PM with many challenges.
Front of mind are the GDP figures due on 25 October. The Government is hoping for an Olympics boost, but regardless of whether the economy has grown or contracted, strategy in the run-up to the Chancellor's Autumn Statement will be closely watched by Downing Street. There cannot be a repeat of the disastrous U-turns in the Budget.
Cameron's Christmas Countdown published this week by Insight also points to several reports landing on the PM's desk. The Leveson Inquiry phase 1 report could regurgitate negative headlines, and investigations into the West Coast Mainline debacle may highlight further incompetence. The behaviour of the banks will be exposed weekly as the Commission on Banking Standards holds its oral evidence sessions.
With these tricky domestic issues, a difficult by-election in Corby, and potentially poor turnout in the police commissioner elections, there are many reasons for David Cameron to be worried. But what he will particularly fear is the renewal of hostilities with the Tory right.
Will their calls for an early referendum on Europe prove deafening? Will rebellions on the scale of the Lords revolt become commonplace, and will they back him on gay marriage? One thing is for sure, Cameron will be spending more time working the tea room than he has ever had to do before.
