The announcement that changes to self employed National Insurance contributions will be dropped is turning Number 10 into a farce.

Just minutes before the Prime Minister would have been forced to answer questions on the controversial proposals, it's been announced the Chancellor would be scrapping plans.

This follows on from an unedifying spectacle where Number 10 officials have scrabbled to distance themselves from the Treasury plans, suggesting that the Prime Minister had no oversight of them before the Budget.

This remarkably public rift in the Cabinet will leave many questioning the effectiveness of a Government that seems unable to talk between departments. 

The absence of an organised and credible opposition, however, means that acts which would under other circumstances be ruinous to the leadership, could have a relatively minor impact on approval ratings.
