The so-called brains behind Boris Johnson said a team of cartoon superheroes could do a better job than the prime minister’s top team.
Senior adviser and hardline Brexiteer Dominic Cummings suggested the country should call on PJ Masks, a team of animated characters popular with young children.
His bizarre remark follows an expected cabinet reshuffle this week.
Leaving his home in London, Cummings started referring to the cartoon when asked about the big announcement on new high speed rail, which he had opposed.
Asked about the reshuffle, he replied: "PJ Masks will do a greater job than all of them put together."
The pre-school animation follows Amaya, Connor and Greg who transform into superheroes Catboy, Gekko and Owlette at night.
Senior ministers including Chancellor Sajid Javid, Home Secretary Priti Patel and Foreign Secretary Dominic Raab are expected to remain in place, while Downing Street has confirmed that Grant Shapps will stay on as Transport Secretary.
The PM is widely expected to cut a number of women ministers from the eight in his 31-strong Cabinet, jeopardising the already poor gender balance.
Fearing she is among those to be cast aside, Business Secretary Andrea Leadsom issued a warning against "male-dominated" environments in a Daily Telegraph article.
A replacement Culture Secretary is also likely as the Government considers controversial changes to the BBC licence fee, with Nicky Morgan saying she expects to go.
