Yes that is exactly the spin I'd expect from the Daily Mail.
I'll reserve judgement as the the article is full of terms like 'the group claim they were told ..' and 'if true then...'
The second half of the article is about Farage's account being closed for the same reason when we now know that isn't true.
Metro Bank have said that they only close bank accounts for commercial reasons and that it remains politically neutral.
At present, it looks like the right wing press are picking up divisive stories to get people frothing and we can't tell yet whether this group, like Farage, are inventing persecution to further their cause.
