Robert Doyle has quit as Lord Mayor of Melbourne City Council and Chairman of Melbourne Health seven weeks after allegations of sexual harassment emerged.

In a statement his lawyers said he "continues to strenuously deny the allegations made against him", and stated that he had been denied the natural justice of innocent until proven guilty. 

In December, ex-councillor Tessa Sullivan alleged the former Lord Mayor behaved inappropriately towards her on a number of occasions.

Two separate investigations are underway: one into Melbourne City Council, while State Health Minister Jill Hennessy has ordered a separate investigation for the Health Department.

He is now in hospital to begin a period of recovery.
