The Telegraph is sometimes colloquially known as the Torygraph. It is indeed decidedly opinionated, in both the opinion it publishes, and the news stories it chooses to cover and the space it gives over to them. It's particularly anti-EU, for example.

But then, news publications have to use some algorithm for story placement, so there's always some kind of bias. A po-faced "objective" newspaper that pretends to no bias at all can be the most insidious.
