A question regarding Schengen Exit checks. If these, alongside UK entry checks were moved to London, wouldn't this mean that most illegal entrants would be unable to reach UK Border Force in the first place, and therefore be unable to claim asylum to a UK official. Instead they would simply be prevented from leaving Schengen, in London and would effectively be required to return the way they came, meaning that moving inbound border checks to London, would not actually enable a loophole for illegal migration.
