Bank of England chief accuses G20 of failing to reform to boost growth

Mark Carney rejects idea that central bankers have 'used all ammunition' against downturn but says system remains strong

Bank of England boss Mark Carney has accused the G20 of failing to adopt measures to boost global growth as he defended central banks and their power to play a role in stimulating economic growth following attacks from critics who say they have run out of ammunition.

Speaking at a meeting of G20 finance ministers and bank governors in Shanghai on Friday, Carney turned on City economists who say the world's major central banks have done all they can to prevent the global economy from slipping back into recession.
