The front-runners clashed in a tech debate last night, but they all sounded basically the same.

Sadiq Khan, Zac Goldsmith and most of the other major candidates in London’s upcoming mayoral elections locked horns last night in a battle to convince the capital’s technology companies that they had its best interests at hard.

Supporting London’s tech industry is a classic piece of motherhood and apple pie. Nobody was going to show up and say they didn’t care about helping start-ups thrive, and there’s very little to choose between them on policy.

Almost all made a point of saying superfast broadband needs to be treated more like a proper utility, though details of how were pretty thin on the ground. All backed an idea (proposed by debate organisers Tech London Advocates, the Centre for London and Tech UK) to hire a chief digital officer for City Hall. And all agreed it should be made easier to hire software developers from abroad, though the mayor’s influence on visa rules is slim.
