Speaking to Sky News on Tuesday (20 April), Immigration Service Union (ISU) professional officer Lucy Moreton said there needed to be a solution to the lengthy checks currently being carried out at the UK border, and stated she was unsure whether something would be done by 17 May.
Asked whether she had concerns the additional checks could overwhelm airlines and ISU members, Moreton said: "Absolutely. You can get an entire aircraft that has failed to do one of the four bits of paper they have to."
Moreton referenced the recently reported six-hour queues at Heathrow airport, which became the subject of debate at a government transport committee hearing last week.
