There should be an end to special treatment for the BBC and Post Office and fewer restrictions on building supermarkets, Washington’s most powerful business lobby group has said while setting out its demands for a post-Brexit US-UK trade deal.

Curbs on firms owned and run by national and local government, the right for tech companies to move data abroad, and secret corporate courts where business chiefs can sue Britain are just some proposals the US Chamber of Commerce is urging Donald Trump to play hard ball over.

The USCC represents more than three million American businesses and, alongside the Coalition of Services Industries, has just published details of the agenda it thinks the US president should pursue.

The document advocates opening vast swaths of the UK economy to the US markets and reflects an American private sector that is less restricted by red tape, government legislation and union rights.

It says: “As like-minded trading partners, the US and UK have the opportunity to craft a 21st Century world-class model agreement that reflects the openness of their respective markets and best practices, and also introduces new innovative elements.”

It comes as Boris Johnson and Jeremy Corbyn battle it out for the keys to Downing Street with the UK preparing to vote in a general election on December 12.

Asked to respond to the trading principles American firms want the UK to stick to, the government acknowledged the USCC had been “ambitious in their demands” but stressed the UK negotiating objectives had not yet been set out.

Trade Secretary Liz Truss told HuffPost UK: “A Conservative government will get Brexit done and seize the opportunities it offers by striking free trade agreements with like-minded countries around the world.

“We will drive a hard bargain and secure the best deals for UK businesses and UK taxpayers. That means maintaining our high standards and making sure British businesses are able to sell their fantastic goods around the world.”
