As soon as votes were counted in the race to be Tory candidate for London mayor, Zac Goldsmith’s problem became clear. He had won comfortably, but just 9,200 party members bothered to vote — compared with the 80,000 who took part in Labour’s contest. Goldsmith praised his party for a ‘civilised and constructive’ debate, unlike the ‘divisive and vicious’ battle won by Sadiq Khan.
