An investigation into the senior medical officer criticised by the Bristol inquiry is due to report back 'shortly', according to the Department of Health.Dr Peter Doyle, a DoH official, has been on extended leave since July when the report was first published.It found that he had placed a dossier of evidence sent to him by Bristol whistleblower Dr Stephen Bolsin into a filing cabinet without reading it.The inquiry concluded his actions had been 'seriously inappropriate'.A spokesperson for the DoH said of the current investigation, which could see Dr Doyle lose his job: 'These things can sometimes take slightly longer than originally anticipated.'
