Conservative in-fighting is threatening to spiral out of control in the wake of Iain Duncan Smith’s dramatic resignation from the Cabinet.

The announcement on Friday evening has triggered an escalating row among some of the party's most senior figures, prompting a series of increasingly strident public statements.

As the Government descends into virtual open warfare, see what each minister has said so far:

It was cruel of the BBC’s Andrew Marr to compare David Cameron and George Osborne to the TV presenters Ant and Dec writes Andy Stowe. One pair does nothing more than host frothy light entertainment shows and engage in elaborate tax scams, while the other plans to hand every school over to private companies; lied about the NHS budget crisis; is destroying social housing; has presided over a rise in the number of people using food banks from 61,000 in 2010-11 to more than one million in 2014-15 and is responsible for dozens of suicides (at least) of people who’ve had their benefits cut.

Marr’s point was that just as even their own mothers find it hard to tell the difference between the two Saturday evening stalwarts, Cameron and Osborne are the joint architects of a strategy to massively shift the balance of power in favour of their class, undo all the post 1947 gains made by working people in Britain and continue a transfer of wealth from the poor to the very rich. Their policy of making it virtually impossible for most people now to find homes outside the private rented sector is a talismanic example of this. If one is in trouble, the other’s career starts to look very uncertain. To use a TV example from long ago, no one wanted to watch Ernie Wise on Saturday night without Eric Morecombe.
