The business secretary blamed the banks for undermining the multibillion-pound quantitative-easing programme by the Bank of England to inject liquidity into the economy.
He said: "There has been a breakdown in the mechanism, in the transmission. It just doesn't get through to companies. We are going to ensure that the new money that the chancellor and the governor of the Bank of England talked about at the mansion house does actually directly reach the companies.
"Given that our leading banks are, frankly, throttling recovery by not making business-lending available, particularly to small-scale companies, we now have to focus single mindedly on that task. How to make sure that the additional money gets through to business."
