We had a Tory NI Minister who didn't seem to realize fully the difference between Nationalists & Unionists a few years back - is it really such a surprise that a mainland newspaper editor wouldn't automatically make the leap from "the glorious 12th" to July KB & pallet burning?
Did a quick check and found out they don't have a NI edition, which would probably have stopped that particular combination of headlines.

Moving off-topic my favourite clashing headlines page was years ago when "Drug Bosses Arrested" appeared beside a picture of Princess Di & an oversized teddy bear.
