They might be able to access the sites that have been used, but will not be able to access the actual communication....to see what the conversation was about.

If a person is suspected of some wrong doing then an intercept warrant needs to be used to get the content of the communication.....and the Home Secretary has to sign such a warrant. This is in line with the Regulation of Investigatory Powers Act of 2000(RIPA).

If someone is really serious about internet anonymity, then there is a company called TOR who manufacture an internet anonymity shield. Apparently these sell well in countries known for repressive government practices(like China).

Anyway these surveillance proposals have now been delayed. Nick Clegg(spit) has said that they are only draft proposals....and that civil rights groups will be given access to the plans before any decisions are made. I bet that fills us all with confidence
