New taxes for the richest 10 per cent, says Nick Clegg Changes could also be made to the rules on stamp duty, capital gains tax and other tax rules, he said. Senior Conservatives are coming around to that argument, Mr Clegg said. "There are an increasing number of Conservatives who understand the value of having fairer tax on high value properties," he told the BBC's Andrew Marr show. I think there is a very good chance that we can make the top pay more tax. Mr Clegg also suggested that the wealthy themselves are willing to pay more. "I think many people of considerable wealth in this country want to play their part," he said. Nick Clegg smiles while being shown the spoof video of his tuition fees apology. Unless the Conservatives agree to some sort of wealth tax, the Lib Dems will not sign off on new Government spending plans after the current four-year round. The Coalition has set out spending plans that run until 2014/15, but talks will begin next year on the next four-year Comprehensive Spending Review. The poor performance of the economy means that more austerity measures will be required to reduce the deficit in the next CSR period. The Deputy Prime Minister said his party accepted the need for more cuts, but said the next package must be balanced with new taxes on the rich. "I will not accept a new wave of fiscal retrenchment without asking people at the top to make their contribution," Mr Clegg said. I don't think you can ask people on middle and low incomes to bear the brunt of this adjustment. George Osborne, the Chancellor, has suggested that could mean a further £10 billion of cuts in welfare spending. Mr Clegg said that was not acceptable to the Lib Dems. He said: "When I hear people from the Right say, all that money should come from the poorest, I'm saying hang on, let's do this in the fairest way possible." I'm not saying welfare is immune from further savings, but the burden has to be spread more fairly.  The ICM survey for The Sunday Telegraph favouring Mr Cable comes at the start of the Lib Dem conference in Brighton where party leaders yesterday went out of their way to highlight differences with their Conservative coalition partners in a range of issues including plans for a "mansion tax" on high-value homes, benefit cuts and public-sector pay. Danny Alexander, the Lib Dem Treasury chief secretary, accused the Tories of being a "blue roadblock" to progress on green issues.
