Check out the BBC. I think it's part an unofficial mouthpiece of the foreign office and the most outstanding example in the world of how to push an agenda subtly through a combination of selective reporting, misrepresentation, false equivalances (an area where the BBC leads the world), combined with a very high quality editorial and reporting staff. But that recipe has an almost inherent left leaning stance. Oh also it's a punching bag for everyone and politicians love to bully it into submission, because it is subject to some level of state control. It's funded by forcing everyone to pay for a TV license.
The BBC World Service is an official mouthpiece of the Foreign Office; it was (at least until recently) funded separately for that purpose, like Voice of America.
Interesting that you conclude with left leaning, when, as I understand it, the BBC is considered to lean right by many, too. I recall a number of journalists remanding BBC leadership over their alleged pro-Israel and right wing bias.
