A confidential Bank Of England (BoE) email, which was inadvertently sent to the Guardian newspaper, has revealed a secret project at the institution looking at 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 and indicated he remains open to staging the in/out vote next year.

The BoE's project was supposed to remain confidential, but was accidentally revealed by the email blunder which revealed details of the project to a journalist.

According to the email sent to the Guardian, the media and most staff were supposed to be kept in the dark about the work, which has been codenamed 'Project Bookend'

The newspaper said the email indicates that a small group of senior staff are to examine the effect of "Brexit" - a British exit from the EU - under the authority of Sir Jon Cunliffe, who as deputy director for financial stability has responsibility for monitoring the risk of another market crash.

In a statement the Bank said the existence of the project should not "come as a surprise".
