Dairy firm Muller Wiseman considers Whitburn and Keith depot closures A dairy firm is considering closing two Scottish depots with the loss of up to 141 jobs. Muller Wiseman is consulting staff and unions at the depots in Whitburn and Keith. The company said that, in the event of closures, many staff may be able to transfer to Aberdeen or Cambuslang. Robert Wiseman agreed to be taken over by Muller Dairy in a deal worth almost £280m last year.
