Background for anyone that doesn't know the Daily Express and the sort of publication it is.
The Express is one of the most notorious papers for anti-immigrant rhetoric and gets very close lying (if not outright lying) in many of their articles. This is the paper that put the shooting of a family in a small town in England on the front page and blamed immigrants. Problem is that it printed the report with no evidence of immigrants being involved and it turned out it was entirely a domestic spat involving only native Englanders.
It should come as no surprise that they were also incredibly pro-Brexit and anti-EU. They don't even pretend to be balanced.
