Supermarket giant Morrisons today warned that 2,500 jobs could be lost after a review found that three of the company's depots may no longer be required.

The firm said its sites in Aylesford, Kent, Bristol and Warrington were at risk of closure.

Workers would be encouraged to apply for alternative jobs in the group with the aim of minimising redundancies, said Morrisons.

The announcement was made as talks resumed with the GMB and Transport and General Workers Union in a bid to resolve a dispute over job security.

The unions suspended a strike due to start today so that talks could continue.

Morrisons Warehouse and Distribution Director, Chris Noone, said the firm had assessed a number of different options during the review.

''These recommendations follow a detailed review of each depot's operational circumstances and fit within the network and an appraisal of their ability to service the Group's future distribution needs.

''We are currently discussing the proposals and consulting with all those concerned with a view to agreeing a plan for the best way forward.''

Morrisons, which recently took over Safeway stores, said it now had overcapacity in its depots.

The GMB revealed details of the depot closure plans earlier this month.
