Britain’s biggest supermarket Tesco (TSCO.L) could cut up to 10,000 jobs as part of its attempts to halt a slide in profits, a newspaper reported. The Sunday Telegraph said up to 6,000 positions would be cut from Tesco’s head offices and the stores it has said it plans to close. Tesco said in late January that up to 2,000 people could lose their jobs with the closing of 43 stores. Tesco recently returned to sales growth, albeit marginally, for the first time since January 2014, a boost for its new boss Dave Lewis, who is trying to compete in an industry price war.
