Guto Harri, the former PM's director of communications, said Mr Johnson also believed Sue Gray was planning an 'orgy of pain, abuse and humiliation' with her partygate probe.
Mr Harri - who has made a series of controversial claims on his new podcast for Global, Unprecedented - recounted Mr Johnson's reaction to Mr Sunak's resignation.
"So, there you have it," he continued."If you really want to know how Boris Johnson felt about Rishi Sunak in the immediate aftermath of his toppling, and the great betrayal of all time as he sees it, there you have it."amid a parliamentary investigation into whether he lied to MPs about parties in Downing StreetThe privileges committee, which is investigating whether Mr Johnson misled MPs about partygate, is expected to publish its findings later this month.
"The police were trawling all over partygate and an inquiry led by an - until then, at least - obscure civil servant called Sue Gray - now a household name of course and a hero of the left - was planning what he described then as an orgy of pain, abuse and humiliation.
"So it wasn't a fight. Obviously they didn't square up to get in the ring. But Boris, rightly, challenged the unelected royal at the time."
