A senior Labour politician has provoked fury after promising to use a mansion tax on Londoners to pay for more nurses in Scotland.
Jim Murphy, the new Scottish Labour leader, wants to hire 1,000 extra nurses using the proceeds of the controversial levy.
Mr Murphy said 95% of the income from a mansion tax would come from the south east of England.
Property experts say Londoners will pay the biggest share of the proposed tax on homes worth more than £2m.
Mr Murphy's pledge was condemned by Labour politicians hoping to be their party's candidate for London mayor.
Hackney MP Diane Abbott claimed the move would 'expropriate money from London.'
Dulwich & West Norwood MP Dame Tessa Jowell said London could not be a 'cash cow' for the rest of the UK.
And current mayor Boris Johnson joined the row accusing Labour of trying to 'mug' people in London.
