It could, and should restrict Murdoch's Empire because it goes against free speech, whatever the people may say or want. The thing is Murdoch and his media empire have been supporting most winning post-war UK political parties (both before and after their election) from Thatcher's to Cameron's. So my guess is that it's in the interest of the PM and his government to support Murdoch because it boosts their popularity and chances of re election, especially so because Murdoch's news outlets are rather popular. It seems to me to be a kind of vicious circle. Even if Murdoch's intentions were good (and they don't seem to be), he should be opposed on grounds of principle, it's always much more reassuring and appropriate in a democracy when you have more than one view to choose from.
