Just took the BBC's quiz based on questions drawn from the 150-page Life in the United Kingdom government book. Living in Blighty for seven/eight years this was easy.
Granted it was only 15 questions but according to the BBC I am entitled to a seat in Whitehall. Tony Blair, move over!
You can test your Britishness here.
You got 14 right!
0-5: Seat in Heathrow arrivals.... 6-10: Seat on the district council......11-14: Seat in Parliament.....15: Seat on the throne
