The Dangote refinery in Lagos — Africa's largest oil-processing facility, owned by Nigerian billionaire Aliko Dangote — has become central to the UK government's strategy for preventing a jet fuel shortage this summer, following the effective closure of the Strait of Hormuz shipping channel since late February. UK Transport Secretary Heidi Alexander confirmed the government is seeking additional fuel imports from the United States and west Africa, with market data firm Kpler reporting that 130,000 tonnes of jet fuel arrived in the UK from Dangote in March alone, with a further 60,000 tonnes en route. The refinery's growing role in British aviation supply chains comes despite recent controversy: Nigerian labour unions accused Dangote of dismissing more than 800 workers for joining the Petroleum and Natural Gas Senior Staff Association of Nigeria (Pengassan), allegations the company denied, though the Nigerian government ultimately mediated the dispute and secured commitments to redeploy affected staff.
