The National Audit Office has warned aircraft could be ground if the UK fails to agree the terms of its divorce with the EU.

The warning over the impact of a no-deal Brexit came from Sir Amyas Morse, Comptroller and Auditor General, of Whitehall’s most senior watchdog.

He was answering questions from a commons committee about the UK’s readiness for a no-deal Brexit.

The London Evening Standard reported that Amyas was asked by Brexiteer Tory Peter Bone if it was inconceivable that planes could be stopped from flying.

“It’s not implausible, it’s not impossible. It could happen deliberately, it could happen by mistake. It depends on how friendly or unfriendly the accompanying music is while all this goes on,” he told the committee.
