How will the number of security lanes be reduced ? Won't that create long queues of passengers waiting to head to departures and reducing the time and money they can spend in the shops ?
The point about Border Force people being replaced by automated readers is a good thing. Since the machines were introduced, queue tines for Brits arriving in the UK have fallen significantly. Putting a passport into a reader and waiting for records to be pulled up is a deeply dull thing to do all day and sonething that can be delegated to arriving pax. Border Force people are meant to be focussed on the more difficult things, like catching people on small dinghies in the Channel, not rubber stamping the right of UK citizens to enter the UK.
