Oh, don't worry - I wasn't complaining about immigrants. I'm talking about people who (according to their CV, and by the sound of their name) had spent all their life in the UK.
One thing you need to watch out for is recruiters "reformatting" people's CVs, possibly without their knowledge, into their "house style". One candidate I interviewed happened to bring an original copy of his CV with him, it was quite radically different to what I had in my hands.
