Workers Vote For Strike Over Night Tube Row

London Underground maintenance and engineering workers have voted to go on strike in a row linked to the new night Tube, the RMT union said. It comes a day after it was announced by new mayor Sadiq Khan that London's all-night Tube service would launch on two Underground lines on 19 August. The strike ballot result is the first faced by the new mayor since he took over from Boris Johnson earlier this month.
