Sadiq Khan appeared to sympathise with Tory mayoral candidate Susan Hall on Tuesday, after she admitted she did not know the price of a London bus fare. The Labour mayor said he did not think the “pub quiz” questions Ms Hall faced in an LBC interview on Monday were the best way of judging candidates, and that Londoners should instead focus on his opponent’s values. Ms Hall, a London Assembly member since 2017, told presenter Nick Ferrari that she doesn’t take buses, so doesn’t know the price of using one. She was also unable to say who owns Hammersmith Bridge, or what the starting salary is for a police officer in the capital.But asked about the interview on Monday, Mr Khan suggested he had some sympathy with his opponent, saying: “I think these sort of pub quiz questions aren’t the best test to see who’s the best candidate to be mayor. “What are their values? What are their past experiences? What’s their vision for our city? What do we know about the track record of their party nationally? All these are the sorts of issues that I’m hoping Londoners will look into.”
