Lord Adair Turner, newish chairman of the Financial Services Authority, which is supposed to keep banks on the straight and narrow, faces his grilling from the Treasury Select Committee today (Bank of England governor Mervyn King is on tomorrow). Turner, a former CBI boss who had to have his arm twisted to take the FSA job, is no fan of PM Gordon Brown, having fallen fallen foul of Brown and his cohorts when Brown was chancellor. Turner produced a huge report on pensions a few years back which was comprehensively rubbished by the Brown gang, chiefly because Brown had screwed up pensions in the first place by abolishing tax relief on dividends paid to pension funds. So Turner can be expected to fire back at Brown, the ultimate regulator of the UK financial system after all, if he gets the chance. Brown introduced the so-called Tripartite 'system' of regulation, sharing responsibility between the Treasury, the FSA and the Bank of England. Hardly surprisingly this led to little more than buck passing. Will Turner choose to remind MPs of this? Bank governor Mervyn King is no fan of the system either as the ultimate responsibility for the banking system used to lie with the Bank. He threatened to resign when Brown brought in the new system. What's the betting that Brown has been on the phone to Turner reminding him of his responsibilities?
