There seems to be a rather mixed news story written recently on Crown
Copyright and CC-BY compatibility:

8 March 2010
'Crown Copyright switches to Creative Commons
It will be replaced by a Creative Commons type licence, devised by
the Office of Public Sector Information (OPSI), which is already used
on data.gov.uk. Jo Ellis of OPSI said: "We have drafted a simple and
enabling set of terms and conditions for the site which means that
data available through data.gov.uk will be re-usable both
commercially and non-commercially. These terms and conditions have
been aligned to be interoperable with any Creative Commons
Attribution 3.0 Licence."'
The story doesn't seem to go into much detail, so it's unclear
whether this is just for data.gov.uk or not... If it is true, then it
sounds like incredibly good news, both in general and also for the
Wikimedia projects.
