BBC reports that Vince Cable is to confirm that the government is moving ahead with plans for a government-backed "business bank" to boost lending to UK companies.
In a speech later, the business secretary will say that he hopes such a bank would "shake up the market" and help boost overall lending to firms.
Also on Tuesday, a report by MPs criticised one of the government's existing business support schemes.
The Public Accounts Committee called the Regional Growth Fund "scandalous".
