A day after declaring she was "a fighter not a quitter", Liz Truss resigned, becoming the shortest-serving British prime minister in history. With the UK now poised to have its fifth leader in six years, we discuss the leadership crisis with political writer, author and leadership specialist Stefan Stern. He says Truss moved too quickly and ignored advice from experts, quickly losing her credibility. This happened in the broader context of Britain's post-Brexit environment, which has left political parties divided. His advice for the next prime minister? "Leave your ego out of it (...) and just appoint the best people that you've got, delegate tasks to them and trust them to get on with it."
