Daniel Hannan: Revolutionary Iran is a threat to our national security – not just regional stability. It must be confronted and defeated.

During the years when the West sought to draw Iran back into the comity of nations, the ayatollahs backed terrorist bombs, cyberattacks, and drone shootings.

Ryan Bourne: The limits of weirdos and misfits

“Bad management” or “the wrong skills” or “incompetent people” are held up as the root cause of bad government.My central gripe is that I doubt this is true.

Stephen Booth: Today, the clock starts ticking down to the next big Brexit deadline

Getting a deal on the future relationship in a mere 11 months will be challenging, but it is not impossible.

Howard Flight: What Johnson should do next. Including dealing with that socialist creation, the BBC.

I suggest the necessary first priority is to sort out the Stamp Duty mess. I would like to see it abolished on residential property.

Richard Holden: The Red Wall. My part in its downfall. How I won North West Durham – Labour since its creation.

We need to build long-term trust to hold seats like this one. We can win again – but we must deliver.

Iain Dale: Downing Street is keeping a beady eye on the BBC

Plus: The landslide that few dared to predict. How I once tried to become Monmouth’s MP. And: Happy Christmas to all my readers

Andy Street: My ten-point West Midlands plan for the new Government

The Prime Minister was right to say many voters have only ‘lent’ us their votes. We must now earn that trust, by ensuring the benefits of life in a post-Brexit Britain reach all communities.

Neil O’Brien: Policies for a new Britain – in which the central point for new Tory MPs is the moors on the edge of Sheffield

Can have a bold enough economic policy that people in these newly gained seats can see the difference in five years’ time?

Henry Hill: YouGov lowers its Tory expectations in Wales and Scotland – but other sources disagree

The Welsh Political Barometer, for example, forecasts a great night for the Conservatives. They can’t both be right.

Daniel Hannan: If you can’t get to a marginal seat, try some telephoning. But please – don’t hang back.

Ryan Bourne: Johnson’s policy prospectus is tainted by interventionism, statism, collectivism – and could be a lot worse.

We economic liberals should be cautiously thankful for the stay of execution that his leadership and manifesto have given us.

David Gauke: An election won. But a year on: “You promised us you’d get Brexit done, but all we hear about is Brexit”

Twelve months on from Thursday’s election, Johnson faces an unpalatable choice – and Cabinet resignations…
