Glaxo plans to restructure its European drug business and is weighing its options for drinks brands Lucozade and Ribena, as it reported a decline in fourth-quarter net profit.
It was reported at the time that the singer had to move into a hotel as the intruders had sprinkled milk and Ribena over much of her flat as well as daubing obscene graffiti on the walls.
As part of the programme, GSK is carrying out a review of its "iconic" consumer drinks brands Lucozade and Ribena, looking at "the best ways to ensure their continued growth".
