Responding to Labour's "mansion tax" announcement, the Business Secretary Vince Cable said it is "good that they've seen sense".
He said that levying a tax on houses worth more than £2 million was the "right thing to do" and that it was an "extreme anomaly" that someone living in a mansion pays the same tax as someone in a semi-detached house in the suburbs.
Ed Miliband has turned political cross-dressing into an art form and has now laid claim to the party's reputation for cutting taxes.
Labour have unveiled two big economic ideas today, neither of them is particularly new and neither of them is particularly effective.
Ed Miliband and his shadow chancellor Ed Balls couldn't have been clearer. Scrapping the 10p rate of tax was a very, very bad mistake.
