Home Secretary Theresa May made a statementintroducing the Draft Investigatory Powers Billthis week, updating and extending the UK's surveillance legislation. It is a draft Bill, so will now be scrutinised in Parliament before the final Bill is introduced in the new year. You can alsosend comments directly to the Home Office.
The Bill (with explanatory notes) is 299 pages long, so rather complicated. Here is a good summary from Wired. I also tweeted some initial thoughts here.
Alongside the Draft Bill, the government also released a Transparency Report on the usage of investigatory powers (e.g. showing that 517,236 notices and authorisations for communications data in 2014).
Parliament's Science and Technology Select Committee has also launched an inquiry into the Bill.
