Volkswagen has reported a steep fall in profits and cut its revenue forecast amid a sales slump in China, as the German carmaker pushes through a brutal cost-cutting programme that includes axeing up to 100,000 jobs.

VW said it expects sales revenue to fall by up to 3% this year, a reversal of a previous forecast for a 3% increase on last year’s €321.9bn (£275.3bn), because of a sales slump in the highly competitive Chinese market.
