Lord Ashcroft: Will voters still give Johnson the benefit of the doubt? We’re about to find out.

Lessons endure from my polling study of our new Prime Minister, carried out six years ago when he was London’s Mayor.

Alan Mak: End child hunger in Britain to help build a fairer society

Independent research found that pupils in schools offering a free, nutritious breakfast boosted their results by an average of two months’ progress over a year.

Suella Braverman: What Johnson learned from a London school amidst deprived communities

His passion for social justice was reinforced by a visit to Michaela Community School – of which I was Chairman of Governors.

Shaun Bailey: We need to find practical ways of cleaning up London’s air

Hitting Londoners with a tax for driving when they have no alternative is unfair. More electric car charging points and improved public transport are needed.

Anthony Browne: Policy Gains from Brexit 6) Getting public procurement to work

At one point, City Hall officials told me the only way to get a project done was to hire external lawyers to take City Hall’s procurement lawyers to court.

Anthony Browne: Policy Gains from Brexit 5) Making regional development more effective

The then EU Budget Commissioner told me that giving control of this funding to national governments would make it subject to “democratic whim”.

Stephen Greenhalgh: Khan is showing a lack of ambition to defeat knife crime

When Johnson was Mayor, challenging performance targets were set – and a credible plan implemented to ensure they were achieved.

Stephen Greenhalgh: The truth about those water cannon

Johnson ordered them, at the request of the police. There was no indication from the Home Office that a licence would be refused.

Penny Mordaunt: London has some serious problems. It needs a serious candidate – namely, Andrew Boff.

I’m backing him to be the next Mayor of London. He will work tirelessly to deliver and he will lead.

John Bald: It’s time to boost the Further Education sector

It is funded at a lower level than schools, and yet is expected to put right much that has gone wrong. Technical courses need higher esteem.

What the London Mayoral selection short-list tells us. And what the successful candidate should do.

No celebrity candidates. No non-Tories. Bailey, Boff and Morrissey have all spent years campaigning, knocking on doors, handing out leaflets in the sun and in the rain.

What sort of Tory campaign is needed for the 2020 election for Mayor of London?

The focus is on the choice of candidate. But the first consideration should be what the message should be and how it can be conveyed.

Victoria Borwick: On knife crime, you can and you must do more, Mr Mayor

The police know where the hot spots are. They must identify the most harmful gang members and can give them a stark choice.

Nick de Bois: Londoners need leadership from Khan on tackling knife crime

Rather than making excuses, a united effort is needed to break up the gangs.

Greg Taylor: England’s most successful Tory politician won’t be directly addressing the Conference next week.

What really matters is proving that devolution has not stalled under Theresa May’s Brexit-focused government.
