My daughter was going to London on business and was detained on suspicion that she was taking someone's job. She was filling in for a co-worker who was unable to complete a 3 day seminar as a trainer. Ironically, that person was also not from the UK. She was cleared for entry after about 6 hours in what she refers to as "Airport Jail".
