Sarah Vine and her co-presenter, author Imogen Edwards-Jones, talk to Boris Johnson's biographer Andrew Gimson on why he feels sorry for the Prime Minister (and why a lot of the bad feeling towards Boris this week stems from 2016, not 2020). Plus, food tsar Henry Dimbleby on why going vegan might not be as healthy as you'd imagine - and astrologer Theresa Cheung peers into the future of Novak Djokovic (and Boris Johnson).
