Brexit presents “unprecedented” opportunities to seal trade deals that are beneficial to both the UK and foreign partners, according to the boss of Britain’s biggest car dealer.

Reporting steady gains in revenue and profit at the half-year stage, Pendragon chief executive Trevor Finn said although there has been “some uncertainty” because of the unexpected result of the referendum, the business has seen no change in sales volumes or enquiries.

Britain leaving the EU and the time it will take to negotiate an exit offer massive advantages to the UK, he said.

“We have got the opportunity to reset trading relations,” said the chief of the FTSE 250 business, which owns the Evans Halshaw and Stratstone brands. “We have knowledge of the terms of every trade deal the EU has as we are still part of that and that gives us a huge, huge advantage.
