The once-good relationship between Bank of England Governor Mervyn King and his most likely successor, Deputy Governor Paul Tucker, is coming  under increasing strain, according to a new book by former Daily Telegraph journalist Dan Conaghan.  It  alleges   King’s management style and and alleged disdain for the financial markets is to blame.

While the Bank of England’s Monetary Policy Committee remains reasonably collegiate, on other matters King more than lives up to the description from former chancellor Alistair Darling that he is ‘incredibly stubborn’, says Conaghan, who now worksas an asset manager.

“The governor can be particularly dogmatic,” he told Reuters. “One of the key things … is the attitude to the capital markets. One of my sources described Sir

Mervyn’s attitude as one of disdain. I’ve heard that repeatedly. Paul is much more pragmatic.”

One tangible upshot of this came at the launch of the Bank’s quantitative easing programme in March 2009, which Conaghan said led to an upsurge in failed trades on the British government bond market, until the central bank found a mechanism to lend back some of the gilts it had bought.
