> change the past

I don't think this is being argued in good faith. I don't think Nigel Farage in particular (among the rabid Leave campaigners quoted to substantiate said backlash _from Leavers_) has changed his position. And I also don't think that Russian "interference" in the sense that Andy Burnham means it is simply the making of public statements that this crowd was opposed to (just as Russian interference in Trump 2016 was also more material).
