I hate to pile on here regarding the Daily Mail (so fun to be one with unpopular opinions) but it's kind of important on a site like this...
The Daily Mail has a truly awful track record for facts. Just google "daily mail lies". Even knowing this I've STILL gotten suckered into believing things I've read there that later turned out to be false. They are a tabloid.
Here are some starting points:

Again, I'm only posting this because of the nature of this site. It's a PSA.
Not saying what they printed TODAY isn't true, haven't read it yet. I AM saying that the DM have been shown to fabricate and/or not research facts and on topics that get clicks.
I saw someone accuse another of putting down the DM on account of not liking what's printed. I would say it goes the other way around. It's easy to believe something that you want to believe because it reinforces your opinions. The DM is demonstrably unreliable.
I'm not saying they have nothing of value. They can provide pictures, links, leads... It's just that a healthy dose of skepticism is required while reading the articles.
