Kinnock did have an image problem (his baldness and his ginger hair worked against him more than his Welshness IMHO - when did we last have a bald prime minister???) but trying to modernise the Labour Party in the '80s was like trying to turn the Titanic.
that is a shallow opinion if ever i saw one, but in answer to your equally shallow question. we have had bald prime ministers, but we have never had a prime minister that was born in wales.
i don't buy the fact that katherine and neil are welsh is the true source of their criticism any more than i believe it is due to their respective looks. however, in katherine`s case, she clearly rubs people up the wrong way and continues to do so. even after running a marathon for charity, some people couldn't applaud her efforts without using the opportunity to stick the boot in once again.
