OIL giant Royal Dutch Shell is set to announce a set of job cuts this week, as new chief executive Peter Voser continues his wave of intense restructuring at the company. But reports that the number of job losses would be as high as 600 were yesterday dismissed. Voser is expected to give details of his restructuring plans at the company’s interim results on Thursday. Earlier this year, Voser kicked off his leadership with a bang, when he axed almost half of the executive directors on the group’s board. This led to the most senior woman executive, Linda Cook, leaving.
