Brexit secretary David Davis is promising businesses that the Government will not end EU freedom of movement in a way that damages the UK’s economy.

The Cabinet minister made the pledge as he suggested that firms should not be “wringing our hands”, but helping the Government forge the UK’s future after Brexit.

Mr Davis also warned other European countries against protectionist measures that would damage both the UK and EU member states.

His speech at the CBI in Cardiff followed concerns raised in the private sector over whether businesses will be able to access the skilled labour they need after Brexit.

It also comes after both he and Chancellor Philip Hammond raised the prospect of the UK paying the EU for access to the single market after Brexit, indicating the Government may accept a deal that concedes elements of free movement for access to the trade bloc.

The Office for Budget Responsibility has estimated that falling migration in the run up to Brexit alone could cost the economy £16bn. Less than 24 hours ago, Director General of the CBI Carolyn Fairbairn said the Government risks hurting businesses if it implements a new immigration system that is too bureaucratic.

Reassuring his audience, Mr Davis said on Thursday: “As we take back control of immigration by ending free movement as it has operated before, let me also say this, we won’t do so in a way that it is contrary to the national and economic interest.

“Because as the Chancellor has said, Britain must win the global battle for talent. No-one wants to see labour shortages in key sectors. That wouldn’t be in anybody’s interest.”

Mr Davis also said he understands that people who voted to remain in the EU are disappointed, but that Brexit must happen. To firms worried about the consequences, he said: “My request to you, leaders of industry here in Wales, and across the whole of the UK, is a straightforward one.

“Help us to write this new and exciting chapter in the country's history. I've said that it won’t be plain sailing and that there will be some uncertainty in the months ahead. But we need to navigate the course together and do all we can to limit that.

“And do so not wringing our hands about what is changing, but projecting confidence about what lies ahead.”

But Mr Davis was also delivered a message to EU leaders with whom relations have been strained as the country prepares to trigger Article 50, launching official Brexit talks.

He suggested the negotiation with the EU on the future relationship with Britain “will be unlike any before, since both sides will start from a point of exact equivalence.”
