The Governor of the Bank of England has called on MPs to solve Brexit's impasse to warn of a growing threat to the global economy.
Mark Carney said that failure to agree to a Brexit deal would trigger an "economic shock" for Britain.

- UK economic growth slowest since 2012

He also stressed the importance for the UK economy of securing a withdrawal agreement with the EU and ensuring a smooth transition.

"The frequency of financial crises in history is at stake Part of the fact that the memories diminish, the financial lobbies mä are financially viable and the costs of relapse in the financial reform are initially invisible, "he said.
