Emotionless Boris Johnson tried to channel his idol Winston Churchill and avoided using the word "resign" to present a "more dignified" version of himself, a body language expert said.
Darren Stanton said the outgoing PM said it was clear that he hadn't wanted to quit, but tried to appear "stoic" on the steps of Downing Street.
He did not show any signs of being upset, unlike previous Prime Ministers such as Theresa May, who cried as she announced her time was up in 2019.
