The former boss of the Royal Bank of Scotland's investment banking arm Johnny Cameron will be formally banned from taking any more top jobs in the City this week.
The Financial Services Authority (FSA) launched an inquiry into RBS's global markets and banking division in April last year and is expected to publish its findings tomorrow. Mr Cameron ran the business for seven years, and was one of disgraced former chief executive Fred Goodwin's key lieutenants.
Mr Cameron is understood not to be planning an appeal against the FSA decision that he should not be allowed to apply for further managerial roles which require the watchdog's authorisation.
He left RBS in January 2009 as the bank reeled in the aftermath of the financial crisis and was bailed out with more than £45bn of taxpayers' money.
Mr Cameron has since made two abortive efforts to return to work in the City. He stepped down from an advisory role at recruitment group Odgers Berndtson after a matter of weeks. Richard Boggis-Rolfe, the managing partner of the prestigious headhunter, said that the company had not "correctly read the public mood with regard to former senior executives of RBS" after UK Financial Investments, the body charged with overseeing the government's stakes in the banks, withdrew its contract to find a new chief executive.
And Mr Cameron gave later attempts to join boutique adviser Greenhill, in April 2009, afte hints that the FSA, which has a right to vet senior City appointments on the basis of whether the candidate is "fit and proper", might veto the move.
Although the ban affects permanent employment in the City, Mr Cameron will be allowed to take on short-term consultancy jobs, provided he has FSA approval.
Alongside the FSA's investigation into business practices in the RBS investment banking operation run by Mr Cameron, the watchdog is also looking into RBS's disastrous acquisition of Dutch rival ABN Amro and the £12bn rights issue to help meet the exigencies of the credit crunch.
Mr Cameron is not the only banker to suffer the wrath of the FSA. David Baker, formerly of Northern Rock, has been banned from the City and fined £500,000. And another Rock executive, Richard Barclay, was fined £140,000.
