Searching Google for UK websites

[dunklk]

OK, most UK residents will go to Google.co.uk to search for a web site, but few select 'pages from the UK' (this is what I'm lead to believe anyway).

So what exactly does Google.co.uk return? Do we just see exactly the same results as if we'd searched on Google.com (aside from AdWords of course)?
Or, would a .co.uk site jump a .com US site for the same search query?

I do not really have much of a clue. I just use .co.uk and then also click on the UK search from the option menu when I search google.
