In regards to the comments posted about Britain no longer being a "world power", that is totally untrue. Ofcourse we are no longer a superpower and of course the empire is gone, but that doesn't mean we're not a world power, far from it infact. Let me throw you some statistics;
The Royal Navy is the second largest in the world in terms of gross tonnage.
The UK has the 3rd highest military expenditure in the world.
The second largest spender on military science, engineering and technology in the world.
The UK's power projection capabilities are second only to the US military.
Britain is a major nuclear power.
And i'm sure you'll agree British armed forces are arguably the finest in the world.
(i'm totally of subject but what the hell)
