The former boss of TSB is seeking to reinvent himself as a consumer champion following a catastrophic IT meltdown which locked 1.9 million customers out of their accounts. Paul Pester has been made chairman of the consumer advisory board at Fairer Finance, which campaigns for banks to give their customers a better deal. Speaking out for the first time since he lost his job over the disaster at TSB, Mr Pester said that running and swimming helped him stay sane as crisis raged. The 56-year-old dubbed the fiasco "a very intense period that all of us would like to have avoided", adding that vigorous exercise helped him get through.
