Melmoth,
i think its also the SWP's position - its not a 'she says that because she's been told to' thing, its a 'she says that because she doesn't feel her constituants should be responsible for what a foreign country decides to spend' thing.
you will be hard pushed to find anyone outside Scotland - regardless of their position on Scottish independance - who thinks that a joint currency union is a good idea. ****, i know a couple of 'yes' people who think its dumb as pork..
