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 has given a press conference after meeting with European leaders at a summit in the Latvian capital Riga.
The prime minister said he discussed proposals for EU reform which he said were necessary to "address the concerns of the British people".
"I believe we can find a way through all of these problems. I believe we can transform our relationship with Europe for the better and that is what I've now embarked upon", he added.
He confirmed that he would be meeting with French President Francois Hollande and German Chancellor Angela Merkel next week as well as the President of the European Commission and other leaders to discuss his proposals further.
"By working together in the right spirit and sticking at it, I believe we can reform the EU and our relationship with it and then the British people will have the final say in an in/out referendum.
"I want to give them a proper choice, staying in a reformed European Union or leaving...and that's why these talks are so important".
