The Liberal Democrats warn that GDP data of this year's third quarter reveals worrying imbalances in the British economy.
Vince Cable MP, Liberal Democrat Shadow Chancellor, says that while overall growth is reassuring, business investment fell in the third quarter.
He says: “Low business investment inevitably means low competitiveness. Manufacturers can hardly be expected to invest in their future when they are struggling to survive the present.
“Exports continue to perform poorly and the economy is being sustained by consumer borrowing, some secured against house prices and some not secured at all.
“The Chancellor needs to set out what the Government thinks is a sustainable level of personal debt rather than let hundreds of thousands of families drift into being dangerously overextended.”
