What proportion of UK searchers use google.com and google.co.uk

Which version of Google do UK searchers use?

I'm sure this question will have been asked before, but I need to know the answer:

Does anyone have an idea what proportion of people using Google to search in the UK use the .co.uk site, and what proportion use the .com site?

Thanks for your help.
