The former Defence Secretary Liam Fox has helpfully pointed out that Conservative MPs account for "five sixths of the coalition, not half".
He called for more help for business through tax cuts and through easing the rules on hiring and firing: measures that would not go down well with Nick Clegg and his party.
Divisions between the coalition partners also affect plans to elect the House of Lords and, of course, reform the health service in England.
The never-ending saga of the Health and Social Care bill continues this week in the Lords when Lib Dem peers will try to make sure the NHS isn't open to European competition law.
Some Lib Dems would be happiest if the entire section on promoting competition was removed entirely from the bill.
But is that at all possible?
A question Carolyn put to the Guardian's Nick Watt.
