It's ironic really that the DM would be the first to demonise somebody who had never worked, lived on benefits and lived, as a single person, in a three bedroom house.
The hacks know what they're doing. The claim that Jo Cox hadn't helped Mair came from a distant relative. The DM can't be sued for lying, because it just reported what a third party had claimed she had been told by Mair. If challenged, the DM could just say they were just reporting what they'd been told.
The article is misleading because the headline and the four bullet points lead the reader to think they are factual. It is well known that many readers never read beyond the headline, the bullet points and possible the first paragraph. There is no clear distinction between the claims and the actual facts, which came up in the trial.
It's all 'nudge nudge wink wink' reporting. The implication is quite clear that immigrants and Jo Cox herself had some responsibility for Mair's state of mind.
