So has reported the Metro:
Although such a levy has been ruled out by both David Cameron and chancellor George Osborne, their Liberal Democrat partners are all for it – as are 57 per cent of those questioned in the Harris Interactive poll for Metro.
The same number would support higher levels of tax on foreign-owned second homes, while 45 per cent back the idea of an increased levy on empty properties.
Some 70 per cent of those polled would back fines of £100,000 for tax dodgers who own properties worth more than £1million.
A Lib Dem spokesman said: “It’s good to hear that people support a mansion tax.”
