If you look up "untrustworthy" in the Dictionary, it will probably list 'The Daily Mail' newspaper in there as an example. They did support Hitler and the British Union of Fascists after all.
I thought this wonderfully constructed satirical meme (Released just after Mo Farah's double gold at the 2012 Olympics)...
...encapsulated what The Mail are all about and how they like to twist the facts to play to the prejudices of their elderly readership.
