Jim Armitage: Lloyd Dorfman's convincing argument for sticking with the EU

Travelex founder Lloyd Dorfman built up his £550 million fortune by making astute business decisions over the past 40 years.

He built his bureau de change empire through two Gulf Wars, the oil shock, 9/11 and the global financial crisis.

He’s a Londoner, puts his cash at risk in his businesses and gives time and money to good causes. So he can’t be accused of being foreign, selfish, a FTSE-100 apparatchik or a Cameron PR stooge.

That surely makes him immune to the usual personal attacks by the Brexiteers on anyone who disagrees with them. And he most trenchantly does disagree.

So I’ll let him do the talking: “From an economic and security point of view, cooperation is better than isolation,” he says.
