A Brexit vote would leave UK exporters facing a £34.4bn “export tax” generated by non-tariff barriers, according to analysis from Remain campaigners.
Sums from Britain Stronger in Europe show an average cost of £79,500 for each British business exporting to the EU.
Business secretary Sajid Javid and former European trade commissioner Peter Mandelson will unveil the findings in Canary Wharf this morning, and challenge Brexit campaigners to set out their alternative to Britain's membership of the single market.
In a letter to Vote Leave, the pair will say: “A campaign to leave the EU’s single market without a plan for an alternative is an act of economic sabotage which would risk thousands of jobs, billions of trade and investment and the future economic stability of our country.”
Brexit campaigner and Conservative MP James Cleverly responded: “The remain campaign are failing to make the positive case for the EU because there isn’t one. With momentum shifting in favour of leaving the EU we are seeing yet more random numbers from the remain camp.’
“The costs of the EU still massively outweigh the benefits and the renegotiation didn't make a dent on cost of the Brussels bureaucracy.”
