Actually, Britain doesn't have a constitution, so you're talking out of your ass.
There's scholarly disagreement about this. As usual it really depends on the definition of "constitution".
As others have noted, there is no single document headed "Constitution of the United Kingdom", so if your definition requires that, then you're stuck.
However, there are some things that would normally be in the constitution (like who gets to be Prime Minister) that aren't actually written down at all. It's tradition, but not a requirement, that the leader of the majority party is the Prime Minister.
More interestingly, some, like F.F. Ridley IIRC, think that constitutional laws must be distinct from other laws in that they are more difficult to change. This is not formally the case in the UK, except that extreme messing with the fundamental make-up of the state will be met by resistance at all levels (not least, in the courts which could just refuse to apply anything too extreme).
Some EU laws do have a special modification process, in that to revoke them, it would be necessary to leave the EU entirely.
There is also, according to Ridley, no reference to a pouvoir constituent, a constitution-forming body that gives authority to the constitution, which is necessary to the existence of a constitution.
The most general definition is that a constitution regulates the relationship between the state and the citizen. Of course, that can be interpreted as broadly or as narrowly as you fancy. After all, the provision of public flower displays is part of the citizen-state relationship.
There's quite a lot of debate, hence the saying that the UK has a one-line constitution (from Vernon Bogdanor, I think):
"What the Queen in Parliament enacts is law."
TV can become a kind of opiate in a way.
What does that make Slashdot?
Goggles showing them in their original condition, and in their original usage, would turn those displays from mere trophy cases of booty into actual demonstrations of history and our global heritage.
Whereas beer googles turn things into trophy cases of booty.
