The UK allows citizens of Australia, Canada, Japan, New Zealand, the US, Singapore and South Korea to use biometric passports to pass through automatic gates on arrival. The government has said in a paper on the UK’s post-Brexit border operating model that it will “ensure that EU, EEA and Swiss citizens may also continue to use our e-passport gates and the existing queueing arrangements”.
This is the paragraph from the Guardian I was quoting from MaizieD, again, I don’t see why the EU wouldn’t reciprocate, do you?
I can see why the EU wouldn't reciprocate, so I'm going to jump in and answer this, I hope that's OK with Pantglas and Maizie.
The UK have decided to let the groups you mention use the e-passport gates when they arrive in the UK. The EU are abiding by their own laws, which state that the e-gates are restricted to holders of EU/EEA/CH passports. This is in the Guardian article as well.
They could decide to change that law, of course, but what would be their incentive for that? To please us, when we have been telling them how much we don't want to be part of their club any more? I expect they don't see any benefit in changing this law at the moment, and that is being portrayed in the pro-Brexit press as them being unfair.
