Top mandarin's bombshell No Deal warning: Food up 10%, police unable to protect public, direct rule in Ulster, worse recession than 2008 says leaked letter

Sir Mark's 14-page letter warns: a) No Deal would result in a 10 per cent spike in food prices and the collapse of some businesses that trade with the EU; b) The Government would come under pressure to bail out companies on the brink; c) It would hamper the ability of the police and security services to keep people safe; d) It would lead to the reintroduction of direct rule in Northern Ireland for the first time since 2007; e) A recession will hit the UK and the pound's depreciation will be 'more harmful' than in 2008; f) Our legal authorities and judicial system would be put under 'enormous pressure'.
