The historian talks battles with cabbies and is in bed by 2am

Best piece of advice you’ve been given? Nothing good happens after 2am. Just go to bed. What would you do as Mayor? Make London the world’s best-educated city. If we could sort that, then we would fix all manner of social problems, make us all happier, boost the economy and save public money in the long-term. There should be a focus on early identification and tailored learning for kids who struggle. Favourite London discoveries? For a history lover every street is resonant: the last duel fought off Pall Mall; the First World War bomb damage on Cleopatra’s Needle; the Hunterian Museum in The Royal College of Surgeons. Got five minutes? Pop in and look at Magna Carta in the British Library.
