Using the flag of the UK.... on campaign material for a UK political party? Jaysus lads, what were they thinking?!
Unless it's used in a jingoistic way (think wrapped around a 19th century military figure that has their boots on the backs of the poor whilst proclaiming Britons never never shall be slaves type of thing) then I really don't get why Labour party members are in fighting about such a thing instead of concentrating on winning a thumping majority.
I think the electorate is smart enough to understand this.
