MacShane said a referendum would be:
"a feast for all the xenophobic and isolationist forces in British politics and be a major boost for the BNP, UKIP and those 'better off out' Tories who want Britain to quit Europe".
"David Cameron… would plunge Britain into the maelstrom of a feast of anti-Europeanism by campaigning to repudiate the decision of the Commons and Lords this year to ratify the Lisbon Treaty.”
"The BNP, UKIP and all other anti-European forces would join in to indulge in months of xenophobic and isolationist hysteria.”

Reading this in the office, it struck us that MacShane's increasingly fiery rhetoric could be a product of 'curry addict synodrome'.
As regular vindaloo-eaters will be aware, the hotter the curry, the less able you are to taste normal foods afterwards - meaning everything needs to be overspiced for you to taste anything at all. Perhaps MacShane just doesn't see anything out of the ordinary in using this sort of language - it's just his default mode of communication...
