Emmanuel Macron has told the European Commission it must tie Britain to EU rules forever during post-Brexit trade negotiations between the UK and Brussels.

France wants to toughen the bloc’s negotiating mandate for the trade talks and force Britain to agree to “dynamic alignment” with EU rules for tax, state aid, the environment and social standards.

Dynamic alignment means Britain would have to change its laws to mirror those in Brussels as they evolve over time, despite the UK having no say in the drafting of those standards after Brexit.

“France wants dynamic alignment across the board,” one EU diplomat said.

The EU is anxious that Britain will use Brexit to embark on a slash and burn of EU regulations and gain what it claims is in an unfair competitive advantage over the bloc by undercutting it.

The commission only asked for dynamic alignment in state aid in its call for “level playing field guarantees” in the draft mandate published on Monday. State aid concerns competition law over issues such as government bailouts, cartels and mergers.

The current version of the mandate wants Britain to sign up to non-regression clauses in tax, the environment and social standards. These are promises to not backslide on Britain’s current rules but are not futureproof.
