Deputy Prime Minister Nick Clegg told ITV News the government may have to scale back its flagship 'Help to Buy' housing policy.
Nick Clegg said a warning from the Governor of the Bank of England - that booming house prices are a threat to economic recovery - must be heeded.
In comments that appear to contradict Chancellor George Osborne's defence of the programme, Mr Clegg said: "If Mark Carney - in view of his concerns about the housing market - thinks we should scale back on some of those schemes, that's exactly what we should do."
