In summary...
Tabloids tend to manipulate stories, can be a bit sexist/racist etc depending on the title, but can be entertaining reads at times.
The Sun - Good if you're a fan of breasts alongside news about death, Bad if you're a fan of not lying about why people die in major tragedies.
Daily Mirror - Better than it used to be. Left wing tabloid, sadly responsible for Piers Morgan. Their parent company is doing good stuff like Us Vs Th3m, but are likely due being pulled in to phonehacking.
The Guardian - Lefty quinola obsessed and enemy of the British state. And the rest of the media. Don't go on Comment is Free online if you value your sanity. Love a liveblog.
The Telegraph - Incredibly Tory, incredibly whiny.
The Times - Think they're more important than they probably are. Good investigations on Sundays, because for historical reasons all are papers are different on Sundays. Tory. Wordy.
Daily Express - Diana/Weather/Xenophonia
Daily Star - The latest on Big Brother, lies and bullshit
Sunday Sport - Not a newspaper but a remarkable weekly work of horrific fiction.
Metro - It's free. PR guff mainly but free.
The Independent - Like a more worthy version of The Guardian. Will do a front page with a black and white photo and the word "DEVASTATION" like it's an amazing statement every other day. Despite being about WHAT REALLY MATTERS, online they're shit clickbait.
The I - Like the Independent, but with some stuffyness taken out. Nothing is longer than 200 words. So, Twitter when you don't have an internet connection.
Edit: I wrote loads more than I expected to there. I tend to read the Graudiad online. (The Guardian is famous for not being able to spell for shit historically)
