Former CEO of office-sharing company accuses Japanese group of abusing its power

Adam Neumann, WeWork’s co-founder and former chief executive, has filed a lawsuit against Japan’s SoftBank, accusing it of abusing its power in order to terminate an agreement to buy $3bn (£2.4bn) of stock from him and other early investors in the office-sharing company.

SoftBank, which is run by Japanese billionaire Masayoshi Son who is also WeWork’s biggest investor, announced in early April that it was walking away from the share tender rescue deal hammered out last October to save WeWork from collapse.
