But now it has emerged that he is the only party leader who would be liable to pay the levy on their property.

Lawrence Hall of Zoopla said: 'Soulless second kitchen or not, Ed Miliband's home is in a desirable part of London and is now worth a lot more than he paid for it before the last election.

Under Labour's plan, people trapped in expensive homes who have no access to savings will be protected from the charge aimed at properties worth £2million or more. Shadow chancellor Ed Balls has promised to hike the levy for homes with over £10million, to ensure they make a ‘significantly bigger contribution’. The £2million limit will rise in line with property prices, instead of inflation ‘to ensure that more modest properties are not brought into the scope of the tax’. Labour has joined the Liberal Democrats in promising an extra charge on expensive properties, to target rich homeowners – especially wealthy foreigners who buy up properties in London. There will also be protection for people who do not have large savings or higher earnings, but who live in an expensive home. The Lib Dems used to argue in favour of a 1 per cent charge on the value of any home worth more than £2million, but there are concerns it would be difficult to implement.
