Diageo workers whose jobs are threatened by a major restructuring proposal are planning to lobby shareholders of the drinks giant at the group's annual general meeting, which is being held in London tomorrow.
Staff from the group's Kilmarnock bottling plant, which Diageo wants to close, will be pressing investors attending the meeting to ask the company for details on its restructuring plans in Scotland.
Unite, the trade union representing the hundreds of staff whose jobs are threatened by the closure of both the Kilmarnock plant and Diageo's Port Dundas facility in Glasgow, also wants shareholders to "demand to see its alternative plan which will keep the threatened plants open".
Diageo has already dismissed the union's proposals to keep the plants open as uneconomic.
Employees are planning to give Diageo chief executive Paul Walsh a giant bottle containing messages from Kilmarnock residents and others calling for the planned closures to be reversed.
At the same time as the London demonstration, workers will protest against Diageo's plans outside the Kilmarnock and Port Dundas plants.
