Mark Carney has become the second senior City figure to fall victim to hoax emails in as many weeks after the Governor of the Bank of England was tricked into discussing a predecessor’s drinking habits with a prankster.

In an exchange that has been published on social media site Twitter, and is likely to raise concerns about email security at the central bank, Mr Carney joked with an anonymous individual pretending to be Anthony Habgood, the chairman of the Court of the Bank of England, about Eddie George’s fondness for martinis.

It comes after the same man tricked Barclays boss Jes Staley into an embarrassing email conversation following the bank’s stormy annual general meeting earlier this month.

Mr Carney was lured into a conversation about bank notes and alcohol with the sender, who was posing as Mr Habgood using the email address anthonyhabgood@hotmail.com .

The prankster, who is a 38-year-old web designer, opened the emails with a discussion of the Bank's new £10 note that features Jane Austen, an image that has recently been described by a biographer of the author as "being like a bracing martini".

When the prankster said he preferred Scotch, the Governor replied: “I will drink the martini and order another two. Apparently that was Eddie George’s daily in take… before lunch”.
