Visitors to the UK from the European Union and the Commonewealth will have to comply with a US-style electronic visa system after Brexit, under plans set out on Monday by Home Secretary Priti Patel.

The plans for a new Electronic Travel Authorisation system (ETA) will make it easier for border guards to screen arrivals and block threats from entering the UK, the Tories say.

It is part of a five-point plan to secure the borders after Brexit and will be launched by Ms Patel and Boris Johnson at a border post.

Other measures include plans to count visitors in and out of the UK and to stop migrants using EU identity cards instead of the more secure passports.

New powers will also be brought in to stop EU criminals at the border once the UK has left the EU and ended free movement of people.

The renewed focus on immigration comes amid alarm in the Tory party about a tightening in Mr Johnson's lead in the polls.

Controlling immigration is seen as one of the areas where the Tories are strongest over Labour. On Sunday, Jeremy Corbyn said that he did not believe that freedom of movement could ever come to an end.
