Scotland's First Minster has said that Mr Carney's predecessor at the Bank of England, Sir Mervyn KIng, had suggested the Treasury could change its approach in the event of a Yes vote.
Alex Salmond told how he had met Sir Mervyn "a couple of years back", and added: "The first thing he said to me was 'your problem is what they say now', meaning the Treasury, 'and what they say the day after a Yes vote in the referendum are two entirely different things'."
Mr Carney, who took over as Governor of the Bank of England in July, has already warned of "challenges" of adopting a shared currency without having "certain institutional structures" put in place.
