Lawyers for former lord mayor Robert Doyle have written to Melbourne City Council indicating they are set to take legal action to prevent the release of a second report into his allegedly inappropriate behaviour.

Melbourne City Council’s chief executive Ben Rimmer wrote to councillors on Friday to tell them to anticipate Mr Doyle would likely use the courts to block release of this second report.

Mr Doyle was lord mayor from 2008 until February this year, when he resigned following sexual harassment allegations made against him by multiple women.

A first report by barrister Ian Freckelton QC upheld some of the allegations against Mr Doyle in March.
