The Lib Dem Energy Secretary Ed Davey has told ITV News he is "delighted" Labour has "seen the error of their ways" by announcing plans for a "mansion tax" on houses worth £2 million:
Our flagship policy is fairer taxes.
People copying you is the best form of flattery.
If Labour are realising they should have supported the "mansion tax" when we argued for it when they were in government and could have delivered it, then I am delighted that they have seen the error of their ways.
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.
