Bank of England Governor Mark Carney has cast doubt on the reliability of some of Britain's economic data, saying he was much more comfortable with official statistics in his native Canada.
Carney said that he and fellow policymakers were wary about official measures of investment in Britain.
"We're not putting full weight on that data and it has to be said that it doesn't entirely feel right that investment is, as measured, falling at a time when we see continued strengthening investment intention," he said.
He also said "a lot of work" needed to be done to raise Britain's flow of funds data - which help measure debt levels across the economy - to international standards.
"I was much more comfortable with the data in Canada," said Carney who was governor of the Bank of Canada before taking over the Bank of England in July.
Mark Carney also said he was concerned by reports that Royal Bank of Scotland mistreated small businesses and said they needed to be investigated fully.
"Certainly we take the view that the behaviours documented in the reports are both deeply troubling and extremely serious," Carney said.
He said Britain's Financial Conduct Authority, which is not part of the Bank of England, was investigating the case which had "to be tracked down to the full extent of the law."
The bank Governor said the pressure on British banks to rebuild their capital levels was no excuse for "predatory restructuring" of small firms, but the scale of the problem did not appear to be big enough to impact Britain's overall economy.
