Boris Johnson's father Stanley, who says he's abroad "1,000 miles away" says he's "sorry that Boris is not one of those candidates" for the Conservative leadership
He says he listened to his son's speech on Skype and was "as surprised as you were by the very last line" - when Boris Johnson said he would not run for leader.
Asked why he thought Boris Johnson had made that decision, his father adds: "Et tu Brute is my comment on that."
"Stabbed by Michael Gove?," the interviewer suggests.
"Et tu Brute was my comment," he repeats.
You too, Brutus?
