One afternoon in early August, Michael Walker was perched on a fake tree stump in a corner of YouTube Space, a studio in King’s Cross, north London, which is adorned with artificial foliage, carpeted in astroturf and lit luminous green. Electric guitars line the wall opposite, beside an Xbox “lounge” and coffee bar.
With his sharp buzzcut, silver studs, big brown eyes and easy east-London twang, Walker looked at home as he directed a team of young videographers. The subject matter – explaining internal Labour-party structures – was less in tune with the edgy surroundings, but Walker was determined to make it interesting. The previous episode of his series Party Time featured him dancing in a black vest, explaining how branches and constituency parties work. (“I might go for more clothes this time,” he says later.)
