"Britain will tell Brussels that it is ready to remain in the customs union after 2021 and until the high-tech infrastructure needed for border control is prepared after Brexit," the British Telegraph reported.
British officials say they may not be ready by 2023, according to the newspaper. "Ministers are at a dead end over the trade deal with the EU, and Eurosceptics are afraid to stay in the customs union indefinitely."
For their part, the Financial Times estimates that "Brexit Britain has closed its doors to foreigners and Prime Minister Theresa May has chosen the harshest possible interpretation of the referendum result. "Those who believe that outside the EU, Britain can once again become the power of the Elizabethan period, let us remember the words of a distinguished British diplomat: that modern economies cannot be open to business and closed to foreigners at the same time," the Financial Times notes.
