The e-passport gates are important to non-European visitors even though they can't use them, because they free up staff to handle the other lines.
in 2008 a critical report slammed inefficencies in the UK border controls, a minister resigned and the whole thing was reorganised as UK Border Agency. In 2013 a critical report resulted in the minister of that year, Theresa May (yes, that one) reorganisng it again and creating Border Force. And guess what, the delays are getting worse. And if you complain you are treated as a terrorist sympathiser.
Anyway, stand by for another name change, but not much else...........
