Rishi Sunak urged to ask ethics adviser to judge Dominic Raab bullying inquiry

Investigation will only establish facts' surrounding the claims against deputy PM, on which Sunak will then rule

Rishi Sunak is facing fresh calls to order an independent judgment on whether Dominic Raab bullied civil servants, after complainants said they were concerned that the inquiry will not make a final ruling.

Raab is under investigation over eight separate complaints across three ministerial departments. The inquiry is likely to be complete within the next month.
