an Australian test cricketer recently arrived here to play for Somerset, and was told at Heathrow his papers weren't in order and sent back to Sydney to try again.
Some people have wondered why they couldn't just give him more papers to fill out at Heathrow, on the grounds that very few Australian cricketers these days are al-Qaeda members. But immigration people don't think that way.
(In fact the last immigration boss tried to manage this sort of thing more sensibly but after tabloid uproar, he was sacked.)
