The Minister for the Northern Powerhouse also insisted the government is making “great progress” in the Brexit negotiations with the European Union.
Mr Berry, 39, described himself as a “reluctant remainer” during the referendum. But the former solicitor has now had a change of heart thanks to the boost in economic performance in Lancashire and the North West.
He said: “The North West, and particularly the Lancashire economy, is going from strength to strength. The latest productivity figures from the Purchase Managers Index show that the region is now growing faster than London following the Brexit vote.
“Lancashire, which has always had a global facing economy, is benefitting from the decision to leave the European Union.
“I was a reluctant remain voter but now describe my self as a ‘re-leaver’ and having seen what has happened since the referendum would now vote for Brexit.
“We are making great progress in our negotiations with the EU. I am convinced Theresa May will secure a good deal for trade with the EU and the wider world which will be good news for Lancashire companies.
“The Northern Powerhouse will be crucial to Britain after Brexit.”
The UK is due to leave the EU in a year’s time.
The economy has been outperforming the gloomy predictions by Whitehall officials in the wake of the Brexit vote.
