How credible (as a news source) is mirror.co.uk?

I found these three articles from another message board that I frequent. I was just wondering if The Mirror was a credible news source or something more along the lines of a tabloid paper.

It’s a tabloid - but perhaps the most credible of them. It took a very strong anti-war stance over Iraq, and has a left-wing tradition. There’s a fair bit of debate among various newspapers over how credible these stories are, with suggestions that the big fat cheque encouraged the guys to make exaggerated or false allegations.

Like all of our ‘red top’ tabloids, the Mirror is just mindless tabloid scum masquerading as a newspaper. Credible? None whatsoever. They’ll print whatever their paymasters tell them to, and the rest is just pin-up girls and stories about non-celebs from soap operas.

Thanks for the heads-up, GorillaMan and ianzin. Those stories did seem kind of sensationalist to me, but I just wanted to be sure.

The Mirror is a low-brow tabloid with strong socialist and statist leanings though stronger on the socialist side.
