Wikipedia is probably a good place to learn a handful of examples and go further down the rabbit hole from there if interested, starting with these sections:

7 Libel lawsuits

    7.1 Successful lawsuits against the Mail
    7.2 Unsuccessful lawsuits
    7.3 Legal action by the Daily Mail

8 Criticism

    8.1 Racism accusations
    8.2 Homophobia accusations
    8.3 Sexism accusations
    8.4 Paying for footage under investigation
    8.5 Byline removal
    8.6 Sensationalism
    8.7 Reliability

https://en.wikipedia.org/wiki/Daily_Mail

Although of course the wikipedia page just has a small number of examples, I'd say that the first words of those 8.1, 8.2, 8.3, 8.6 subheaders above, and lack of 8.7, do a decent job of surmising the Daily Mail.
