“And the details of any transitional arrangement matter: the economic relationship the U.K. and EU has during this time-limited period must match as close as possible the status quo.”
The letter is due to be sent from Britain’s five leading business groups, the CBI, the British Chambers of Commerce, the Institute of Directors, the Federation of Small Businesses and the manufacturing group, the EEF.
Sky News reported that the five groups were increasingly worried that Britain could leave the EU without a deal. Prime Minister May won a modest reprieve on Friday when EU leaders signaled they were ready to move the negotiations forward in the coming months.
A spokeswoman from the Department for Exiting the European Union said the prime minister had been clear that an implementation period would help minimize disruption.
“We are making real and tangible progress in a number of vital areas in negotiations,” the department said in a statement.
