The Times really struggled with the Ch 4 news story as well.
The Times and Telegraph either knew the poll was paid for by Reform and avoided publishing that fact. Or they don't do any due diligence on a story before they print it.
Similarly they either they knew the photograph was taken by a member of the Patriot groups and didn't mention it, or completely failed to do any basic enquiries.
I suspect they knew in both cases and hoped it wouldn't come back to bite them on the arse.
