Andrew Mitchell: A 28-day time limit on immigration detention would save money and make the system more just

We remain the only country in Europe to detain people indefinitely for the purposes of immigration enforcement, at large financial and human cost.

Charlie Elphicke: The customs debate is pointless if we aren’t ready with a new system. Government is failing and must succeed.

When I asked freight experts at a Treasury Select Committee hearing if we still had enough time, they said: “You would have to get a hell of a wiggle on.”

Henry Newman: No more delays, Prime Minister – it’s time to make a decision on customs

There are two options under consideration. One in particular, the partnership model, is unworkable and unacceptable. It should be put out of its misery.

WATCH: Wallace and Jones clash over the ‘hostile environment’ policy towards illegal immigration

“Are you seriously saying we should not have a system that checks whether people are legitimately in this country?” our Executive Editor asks the Guardian columnist.

Andrew Green: We need to see the Government’s planned post-Brexit immigration framework

Without a firm, stated base, we are vulnerable to being pushed around by the Commission. Ministers might find it uncomfortable to talk numbers, but they must.

Is the Home Office blunderingly incompetent, or deliberately obstructive? Bad news: it’s a combination of both.

If there’s to be no border in Ireland, and Britain is to leave the Customs Union and Single Market, it follows that there must be a customs border on the Irish Sea.

Daniel Hannan: Johnson – a Tigger among Eeyores – is right to restate the positive, uplifting vision of Brexit

Many voters – Leave and Remain – appreciate his spirit of boldness, and want to move on from past divisions, not reopen them. There are opportunities to be grasped.

Kieran Mullan: A good deal is within our grasp – including on the Northern Irish border

For political reasons some ignore practical solutions and pretend the current EU arrangements are perfect. Such obstructionism helps no-one.

Overall, our new report suggests that public attitudes towards immigration – and indeed leaving the EU – are not fuelled by racism or intolerance.
