Ex-GSK boss Emma Walmsley is hired to run US tech giant HP despite having no experience running a hardware business

Walmsley, who ran pharmaceutical giant GSK for nine years and earned more than £80 million there, will take over at HP on 4 January, succeeding interim chief Bruce Broussard, who moves up to board chairman. HP is battling a global memory chip squeeze that pushed PC shipments down 16% in its third quarter, with the industry expected to shrink further next year. She brings no tech hardware experience but has sat on Microsoft's board for seven years.
