Google.co.uk vs pages from the UK - anyone noticed any changes?

[Digirank]

We've started to notice some changes in the rankings of Google UK and Google pages from the UK.

Pages from the UK have always typically ranked higher, however it seems like these are slipping, and Google UK pages (pages from the web) are climbing.

We've noticed a similar thing happening in the Bing/Yahoo algorithm as well.

Just wondered if anyone else has anyone else noticed this?

Thanks
