It depends upon what you see 'fake news' as being. People can be misled just as easily by bias as they can be by untruths.
For example, if a newspaper only reports on the jingoistic statements of pro-Brexit politicians, while failing to report the concerns of businessmen, union leaders and many others, it's not giving its readership a true picture of the debate.
Similarly, if a newspaper carries many stories about the negative aspects of immigration from the EU, while failing to report on the many studies that show such immigration has totally revitalised towns such as Grantham and Thetford, it's again providing a false picture in total.
Deliberately choosing to use headlines such as "Romanian immigrant convicted of . . . ", rather than using "Man convicted of . . . " also risks inflaming xenophobia and racism.
The Daily Mail also has an appalling record on checking the information they receive before committing it to print:
