Love it or hate it...

Marmite of course.  People are up in arms because Unilever. who own Marmite, among many other products, intend to increase their prices to supermarkets and other outlets as a result of the value of the pound falling against the dollar.  Now there's no doubt that a weak pound will mean higher costs for imported goods and that. to a greater or lesser extent, this will be passed on to the consumer, but what I can't understand is that Marmite may well be owned by Unilever, but it's made up the road in Burton-on-Trent, so how has the cost of manufacture been affected by the exchange rate?
