The Bank of England boss urged bank chief executives to step up their plans for a no deal Brexit during a private phone call on Tuesday, Sky News is reporting. He is understood to have told banks to intensify their readiness for Britain to leave the bloc on WTO terms.
The UK has already formally left the EU and negotiators on both sides have until the end of this year to agree a deal setting out their future relationship.
EU chief negotiator Michel Barnier confirmed earlier this week the bloc is "open" to a two-year Brexit delay followed tense talks between the UK and EU sides.
But Britain's chief negotiator David Frost insisted the "firm policy" of the Government remains not to extend beyond the end of the year.

Brexit warning: Nissan UK plant ‘unsustainable’ without EU trade deal [COMMENT]
The 7,000 workers of the UK's largest car manufacturing plant rejoiced last week after surviving a global cost-cutting restructuring that saw the closure of the Japanese firm's Barcelona facility.
A Nissan spokesman said at the time that "Sunderland (remained) an important part of our plans for the European business."
But in an interview with the BBC, Nissan's global chief operating officer Ashwani Gupta warned the company would not be able to stand by its commitment to the Sunderland plant if the UK left the European Union without a trade deal that enabled tariff-free EU access.

Mr Gupta said: "You know we are the number one carmaker in the UK and we want to continue. We are committed.
"Having said that, if we are not getting the current tariffs, it's not our intention but the business will not be sustainable.
"That's what everybody has to understand."
