Sainsbury's is to cut 800 jobs as it becomes the latest supermarket to restructure its operations in the face of tough trading conditions.

The chain said it will review its department and deputy manager positions, with more resources invested into other shopfloor roles.

It will also replace night shifts with early-morning and evening shifts in some stores in an effort to improve availability for customers.

Redeployment opportunities will be made available but Sainsbury's said it expects the proposals will result in around 800 fewer roles.
