Following a recent request from a colleague as to a good way of keeping up to date with the mass of legal changes, especially in the field of Intellectual Property, I recommend the IPKat blog as a good start, which can be found at:

The following sites post daily changes:
The live feed for the UK Supreme Court is at:
http://news.sky.com/info/supreme-court
A daily feed for legal updates in many areas of law:
www.lexology.com/
For published legal cases and other legal authorities:
http://www.bailii.org/
I hope the above assists.
