A confidential Bank of England (BoE) email, which was inadvertently sent to the Guardian newspaper, has revealed a secret project at the institution assessing the economic risks posed to Britain if the country votes to leave the European Union.
The existence of the Bank's project emerged as the Prime Minister insisted he was "confident" of securing reforms in Brussels after meeting with European leaders at a summit in Latvia.
David Cameron is meeting European leaders today for the first time since securing his re-election.
Speaking ahead of the meeting, the prime minister said it was an opportunity to start some of the discussions about the reform of the European Union.
"There will be ups and downs, you'll hear one day this is possible, the next day something else is impossible".
He added that one thing that will be constant is his "determination to deliver for the British people a reform of the European Union so they get a proper choice in that referendum".
The Bank of England has launched a secret project looking at the economic risk to Britain if the country votes to leave the European Union.
