yes i think the cuts at UKBA have had an effect, at Manchester airport I've always arrived i think at around 7am on my way back from the phils and I've never seen anyone at customs once you've collected your luggage.(apart from the above someone checking peoples tags on their luggage)
one of the first times i went, I bought 4 reams of cigs for my brother and put them in my suitcase, i didn't know what the duty free allowance was then, anyway collecting my case at Manchester airport, some cheeky
had forced one lock on the case open, and nicked 2 packs of cigs from a ream
