Conservatives? The UK's current government is not a conservative one.

Though I don't think the political leaning of the party in power matters here, as this is what governments do in general. Find ways, and justifications, to expand the scope of their power, often by using "desiring safety for insert demographic here (usually children)" and managing to get it through. Often without thinking what future, potentially more tyrannical governments, might do with that power.
