My Tax Justice Network colleague has a typically thoughtful and measured article in the Guardian this morning discussing how we tackle tax havens.

Having considered many of the available options he turns to the UK - Swiss tax deal that comes into force next year, concluding:

Chancellor George Osborne in his budget speech in April described tax evasion and avoidance as "morally repugnant". But his tax deal with Switzerland, as a fiscally useless spoiler, is a tax evader's dream. This government must repudiate it immediately. If it doesn't, Labour must commit to abolishing it — or hang its own head in shame.

I have to say he's right. Read the whole thing to see why.
