Alex Norris, minister for border security and asylum, said the government “worked closely with our European partners to ensure the rollout goes as smoothly as possible”.

Transport minister Keir Mather said the government’s priority was to “minimise disruption for travellers and hauliers, particularly at our busiest border crossings”.

The Port of Dover requested its EES kiosks do not initially require users to answer questions about their trip such as whether they have sufficient funds or a return ticket.

Those requests were passed on by the UK government to EU officials but no confirmation has been received, it is understood.
