And after a Tory-led government came to power...
What's that got to do with it? (genuinely interested).
One of the first things the new government did was start the wheels turning on what became the Protection of Freedoms Act 2012. Whether you think that law went far enough or not, I suspect most here would say it took steps in the right direction on numerous issues where the previous New Labour administration had eroded rights and liberties. A few of them were big-headline, fundamental issues, but there were quite a few relatively minor concerns addressed as well, such as the excessive use of surveillance by local authorities that we're talking about here.
Given that coalition government is not the norm in the UK, I suspect politically it was more important that this was something the two parties could agree on as an anchor than anything else, though no doubt many of the incoming Lib Dem MPs and at least some of the Tories were no fans of the previous situation anyway.
