David Cameron and George Osborne are both singing from the same hymn sheet about the fact that there was no Granita style deal between the two of them in their joint interviews with the Mail
and the Telegraph
. The big difference between Cameron and Osborne and Blair and Brown is that Osborne was never the senior partner and as the younger man need not fear that he’s missed his turn.
Probably the most likely source of future tension between the two of them is foreign policy. Where as Cameron is a classic Conservative when it comes to foreign policy, see his Berlin speech which was depressingly Hurdian, Osborne’s world view is far more modern. In opposition this kind of difference is not that important but in government it could become a real problem.
