Polys Haji-Ioannou has won the latest round of legal action against Nobu Su and his mother Toshiko Morimoto, but failed to persuade the judge that the freeze on her assets should be continued.

At a hearing in London on Thursday, Justice Michael Burton granted the claimants leave to take further legal action against Morimoto and the two co-defendants, shell companies Cresta Overseas Ltd and Portview Holdings Ltd.
