Polly Toynbee is wailing in her column this morning about the Chancellor’s U-turn. She reckons it is the “FT Wot Won It” and that Digby is Jones is the Thatcherite vetoing policy in Brown’s Big Tent. On one point Guido is in agreement with her; Labour claim they will take £650 million from non-doms, while the Tories claim they will squeeze them for £3.5 billion. Labour will tax them only after they have lived in Britain for seven years, whereas the Tories will tax them from day one.

So won’t the Tory policy drive more globally mobile wealth creators out of London? Isn’t Osborne’s policy worse for the City and more punitive?
