British Prime minister Theresa May | Leon Neal/Getty Images Secret Brexit memo: UK won’t get single market access French will be ‘difficult,’ according to notes held by Tory adviser.

The U.K. is unlikely to be given access to the EU’s single market after it leaves the bloc, according to a memo carried by a Conservative Party adviser.

The note, photographed being held by an aide to Tory party vice chairman Mark Field, said the U.K. would get “transnational” controls after Brexit that would give Britain access to the single market for a limited period, the Telegraph wrote Monday.

It says that whereas a deal on manufacturing would be "relatively straightforward,” an agreement on services, including the financial sector, is likely to be "harder.”

The note suggests that Britain will opt for a "Canada plus" trade deal with the EU, adding that remaining a member of the European Economic Area would be "not good.” A so-called Norway model seems unlikely too, according to the notes.

It also says the position of the British government could be undermined by the “difficult” French negotiating team and the implementation of Article 50, which formally triggers the process of leaving the Union, would be “difficult."
