The Guardian A is for asylum seeker.
B is for bogus.
A word banned two years ago by former immigration minister, Mike O'Brien, for being pejorative. C is for Campsfield House, near Oxford, the largest immigration detention centre. It is run by Group 4 and has been the scene of hunger strikes and disturbances. About 1,000 asylum seekers are detained because there is evidence they will abscond or because they face imminent removal. About half are held in Haslar and Rochester jails.
