Mr Cameron ruled out Liberal Democrat proposals for a mansion tax, saying they were "not going to happen."
Speaking on the Andrew Marr show the Prime Minister said;
.I don't actually believe we should be a country where if you work hard, you save, you buy yourself a house, you try to pay down the mortgage, you save and invest into that house, I don't want to be a country that comes after you every year with a massive great tax. So that is not going to happen.
What we have put extra tax (on) is when people buy very expensive property.
