Only one option?
I read the Economist, Times and the Guardian.
The Times, being bipartisan, makes for better reading, but on the other hand, the quality of the articles in the Guardian is very high.
The Economist is of course the ultimate news resource, and reading that once a week gives you more knowledge than any newspaper could...
I wouldn't call a Murdoch paper bipartisan.
The Daily Mail because, to me, it seems equally working class and middle class. So, I don't feel like I'm 'reading someone else's paper' (My mom was working class and my dad is middle class) Plus, it's easy to read, regarding size.
Although Quentin Letts really lets the paper down sometimes (he's a writer) with his holier than thou attitude.
I read the Guardian online because I hate the broadsheet size. It's informative and it's like the newspaper equivalent to the BBC.
I've never heard a Tory call the Telegraph crap before! I personally like to read the Telegraph for a good dose of intellectual right-wing thought every now and again.
The Mail on Sunday, the Times or the Telegraph during the week, sometimes the Economist. Since we're smashing those conformities and metanarratives, I'd also like to add that the Spectator, Samizdata, FHM and the Microsoft Developer Network are also grand, regular newspapers I read, even if they don't contain news or paper.
The independent - its just the lay out is much nicer and esp the size was a determining factor. Plus they talk loads more on the middle east politics which is more of an interest to me.
