quick point 1: Murphy is a crazy left winger, seriously, try following him on twitter and not exploding.
quick point 2: Seriously, income & profit generated from a country should be subject to the tax of that country. I don't know why this isn't obvious to everyone, especially HMRC/the Treasury when they write the rules.
final point: I'm not sure companies should be taxed at all. Just make it law that anything accounted for as "profit" must be paid as dividends, and charge people income tax on the dividends. Do this at source, like PAYE, for all dividend payments leaving UK-active companies, even the ones headed to foreign citizens. (this would mean companies could re-invest in growth for free, but that that growth would have to take place in the UK.) Subject all "brand value" payments, and indeed all other transfers abroad, to scrutiny / valuation (should be easy for big companies, as there's only one brand.) This would work anywhere, not just in the UK.
