Matthew Barber: How catching drug dealers cuts crime more generally

A string of bicycle thefts could be a coordinated plan, with those stealing the bikes paid with a small amount of Class A drugs.

Susan Hall: The Prime Minister is serious about defeating the drugs gangs. But the Mayor of London is not.

Thousands of teenagers are exploited through County Lines. The Metropolitan Police force area is the largest exporting hub to the rest of the country.

Neil O’Brien: Fifty shades of conservatism

It’s a bit like the roof of Parliament’s Westminster Hall: which is held up by a lot of huge, ancient beams all resting on each other.

Marshall Tisdale: Scotland’s drug statistics are a call to arms for radical reform

We need to stop treating addicts like criminals and forcing people who want to experiment to forge contacts with black-market dealers.

Thomas Kerr: Scotland needs radical change to tackle the drugs crisis, and the Tories offer it

Our premise is simple: users don’t need a plan to help them manage their addiction, they need a life plan to help them end their addiction.

Adam Honeysett-Watts: After three years of gloom under May, it’s time for fun with Johnson

We need to redefine our purpose, move forward with our global partners, unite the UK – and defeat Corbynism.

Howard Flight: Why the time has come for drug legalisation

Confessions of use in their youth by politicians raises the case for controlled legalisation – at least of ‘soft’ substances, if not yet of hard ones.

Robert Halfon: Under our new leader, we must prize social justice above social mobility

We must tackle causes of poverty, not symptoms: educational failure, worklessness, family breakdown, debt, addiction, disability, exposure to crime, poor housing.

Iain Dale: Johnson – unstoppable now, unless he unstops himself

Many will hope that Gove and Hunt duke it out in a constructive way for the right to take on the man who is the clear winner from the week’s events.

Bob Seely: Saving Britain billions. Ideas for the contenders in this leadership contest.

This is a contribution to the debate – now let’s see what the candidates offer during the week ahead.

Andy Street: My seven tests to find the right Prime Minister for the West Midlands

They are chosen not from a factional or ideological standpoint, but from what I see while doing the job of Mayor.

Edward Davies: The next Conservative leader must make social justice their top priority

Government should be passionate about self-reliance, but we must also recognise the transformative power of an enabling state.

Victoria Borwick: We must invest in the next generation to cut knife crime

These opportunities and options should start far earlier in children’s lives, enabling a twin-track of skills training.

Rachel Wolf: The Government’s porn crackdown. It sounds great. But it won’t work.

If we can’t think of anything that’s going to do real good, maybe we could act like true Conservatives for once – and choose to do nothing at all?

Politicians must decide whether their priority in response to knife crime is ‘do something’ or ‘do something effective’

Being seen to be tough is superficially appealing, but prioritising solutions that actually work is a far better service to the public.
