Tory Phillip Hammond (NB not George Osborne) has just been on BBC News 24 skating around questions regarding the Tory promise to "recognise marriage in the tax system". They will soon announce what form it will take. But it is clear the Conservatives are going to encounter some significant problems between the moral appeal of the policy to their natural constituency on the one hand, and the social justice appeal by which they have sold it, on the other. They are caught between a rock and a hard place, and their love affair with the policy may soon be "on the rocks" as a result.
