Patrick Spencer: Some advice for the new Conservative leader. Stick to these three ideas to boost productivity.

The new Chancellor should stick to the basics of cutting taxes, spending more on education and rebalancing growth outside of London.

Iain Mansfield: Brexit by October 31. Stop using the Left’s language. And stand for skilled workers. Essentials for our next Prime Minister.

Which candidate can devise and push through the policies needed to unite the Tory shires with the Leave voters of the north?

Clark Vasey: Only Johnson can deliver Blue Collar Conservatism

He is the only candidate who can further the work of the project to which Esther McVey and I are so committed.

Stephen Crabb and Desmond Swayne: The next Prime Minister must uphold Britain’s commitment to overseas aid

It’s so much more than charity: it bolsters our diplomacy and nurtures trading partners and military allies around the world.

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.

Profile: The unusual Rory Stewart, self-declared contender for the Tory leadership

His critics claim his appointment as International Development Secretary “could lead to the death of thousands of the world’s poorest people”.

Stewart is appointed DFID Secretary

He is one of the few middle-ranking Ministers who, while others were fleeing for the hills, girded himself up – and went out to fight for May’s Brexit deal.

James Frayne: What polling does and doesn’t tell us about voters and the environment

There are clearly dangers in accepting the terms set out by green activists – who essentially argue that we can only protect the environment by slowing growth.

WATCH: Hannan – “The surest way to eliminate poverty in the world is through freer trade”

He suggests that Western observers very often misread the situation in developing countries in a manner which deprives the latter of agency and opportunity.

Clark Vasey: Welcome to the Blue Collar Conservatism relaunch

Esther McVey with the support of MPs from across the party is refreshing and renewing the project.

Lord Ashcroft: The space for a new party isn’t just in the centre of politics

At the same time, my research shows some of the hurdles any theoretical new movement will have to cross if it is to survive contact with reality.

Huw Merriman: To ensure that the aid budget is spent carefully, let DFID, not the Foreign Office, control it

The Taxpayers’ Alliance is right to demand responsible stewardship of valuable resources. But we should not mess with the aid rules.

“No-one voted for Brexit to become poorer.” Really? We vote to deny ourselves money all the time.

Security, cohesion, integration, solidarity: all are intangible. But we pay – literally – to gain them. Why single out self-government?

Nicholas Daniels: British aid should primarily be about investments, not handouts

Ultimately, it is economic growth not traditional aid which will support the growing populations of the developing world.

Lord Ashcroft: Special Report: St Helena – the island of fading hopes and dreams

It is an attractive destination, with a friendly population and a fascinating history, but it has been badly let down by officialdom.
