During the Emma Peel series it looks like Steed did not have direct superiors as he did in series 1 to 3 and series 6. Nevertheless he gets orders from The Ministry, or some officials of the ministry or ministers themselves such as in Silent Dust or The Master Minds.
In The New Avengers Steed's friend Thomas "Tommy" McKay seems to be in charge (TNA Hostage) of the department Steed is working for.
