Man-Machine Investigatory Powers bill (Snoopers' Chapter) becomes UK law

[Second Summer]

After more than 12 months of debate, jostling and a healthy dose of criticism, the United Kingdom's new surveillance regime is officially becoming law.

Both the House of Lords and House of Commons recently passed the Investigatory Powers Bill – the biggest overhaul of surveillance powers for more than a decade – and it is due to receive Royal Assent later today.

The Queen has now also given her royal assent. 48 different official bodies will have access to our Internet browsing history, and no warrant is needed. These include police forces, the Foods Standards Agency, the secret intelligence service, fire and rescue authorities, NHS trusts and boards that provide ambulance services.

The browsing history of the whole of the UK would constitute quite a valuable dataset, I would think. It would be a highly prized target for hackers (freelance and those working for foreign governments), and it could be used e.g. for blackmail purposes. People with access to these records could be targeted and be persuaded (by foreign agents or criminals) to provide unauthorized access.
