An employment tribunal between the Co-operative Group and its former chief procurement officer Kath Harmeston has seen Ms Harmeston claiming more than £5m in damages for unfair dismissal.
Ms Harmeston claims she was sacked after she blew the whistle on alleged procurement non-compliance at the Group.
The Group deny this and say she was dismissed because her procurement activity was non-compliant with Group policy and her claims are “an attempt to mask her own serious misconduct”.
