How can David Cameron fix the Tory row over the Budget?

Last week’s Budget was supposed to be boring, but is still splashed across the front pages of the newspapers this morning. It was supposed to be crafted so that no Tory MPs could raise a rumpus, yet it has led to the resignation of a Cabinet minister and the opening up of a yawning split in the Tory party. This row between the Tory leadership and those supporting Iain Duncan Smith isn’t officially about Europe, though the referendum has undermined the foundations of the party enough to make this row seriously destabilising for the leadership.

David Cameron will use his statement on the latest European Council meeting to reassert the compassionate Conservative credentials of his government, something he tried to pitch as the key theme for his second and final term as Prime Minister.
