Henry Newman: Cummings understands the need to drastically reform Whitehall

It’s not an optional extra – it’s crucial to delivering an effective Brexit and making the most of the opportunities outside the EU.

Henry Newman: There is a path for the new Prime Minister that leads to Brexit. But it’s very narrow – and must be taken at once.

There are four possible approaches he could take on Brexit. Not all of them lead to success.

Henry Newman: Johnson must learn from Lincoln, and appoint a Team of Rivals

He will inherit a precarious Parliamentary position, and time for agreement is growing very short.

Henry Newman: The Alternative Arrangements Commission offers the best route through the backstop problem

There are real, viable answers to this sticky problem. But rebuilding trust may be as hard as resolving technical questions.

Henry Newman: Remainers are desperately spinning the result. But the moral of this election is that Britain must now leave.

Ken Clarke summed it up recently when he argued that there was now no chance of Britain being a stable member of the EU.

Henry Newman: The Tory poll collapse is nothing to do with May’s Withdrawal Agreement. MPs should vote for it – and deliver Brexit

A basic problem remains unaltered – that there is no Commons majority for a No Deal Brexit. This point has been well made by Ann Widdecombe.

Henry Newman: Most Conservatives don’t like it – but talks with Corbyn offer a way of breaking the Brexit stalemate

It may be unpalatable, but there’s no point arguing about retaining customs union membership if we can’t get out of the EU in the first place.

Henry Newman: No free movement. No second referendum. Brexit gained. What would happen were the Prime Minister’s deal passed.

Now, the best option for the Prime Minister is to try to work with Labour. Unless, of course, her backbench critics rethink.

Henry Newman: What will the EU do now? Force No Deal? Offer a long extension? Or even a short one?

Now more than ever, it’s Brussels and not the Government which is in the driving seat – and we don’t know which way it will turn.

Henry Newman: Conservative MPs should beware handing Labour the victory on Brexit

If they reject the Withdrawal Agreement a third time, a deeply divided Opposition could yet get the credit for a soft departure.

Henry Newman: Bercow has demonstrated he will do anything to frustrate Brexit. So it’s time for MPs to smell the coffee.

Critics of the deal need to compromise and accept the actual choices on offer. Refusal to do so risks an outcome far worse, or no Brexit at all.

Henry Newman: Why the revised deal’s changes to the backstop are significant – and offer Britain a route out

The final paragraph of Cox’s advice notes that in some circumstances the UK could suspend or exit the backstop under the Vienna Convention on the Law of Treaties.

Henry Newman: Thirteen myths about the Prime Minister’s deal

It is not always given a fair assessment, particularly against the other options actually available. Those open to persuasion should look at the facts before it’s too late.

Henry Newman: Get real, Eurosceptics. Your choice is May’s Deal – or no Brexit at all.

If her revised plan fails, the most likely outcomes are an even softer Brexit or a second referendum.

Henry Newman: A new bout of political instability hits Labour – but does it change the Brexit arithmetic?

At least four Tory MPs have apparently been placed on defection watch including Anna Soubry, Sarah Wollaston and Richard Harrington.
