This afternoon Labour publish the motion for Tuesday's House of Commons vote on the Mansion Tax and challenge the Lib Dems to back it.
The Lib Dems have repeatedly said they support a Mansion Tax. On Tuesday the Lib Dems will be judged on what they do, not what they say.
Chris Leslie MP, Labour's Shadow Financial Secretary to the Treasury, said:
"If Nick Clegg and Vince Cable really believe in a fairer tax system they should back our motion in support of a mansion tax on pro perties over £2 million to pay for tax cuts for millions on middle and low incomes.
"After going along with a Tory tax cut for millionaires, a failing economic plan, a VAT rise and a trebling of tuition fees this is a chance for the Liberal Democrats to finally vote for something that was in their manifesto."
The full text of the motion is as follows:
“That this House believes that a mansion tax on properties worth over £2million, to fund a tax cut for millions of people on middle and low incomes, should be part of a fair tax system and calls on the Government to bring forward proposals at the earliest opportunity”.
