A group of bureaucrats and politicians in the planning, works, energy and finance ministries stand accused of manipulating the state’s policy and procurement procedures since 2012 to steer control of the energy sector into the arms of Xaris Energy, a company closely linked to the ruling Swapo party. Xaris is partly owned by Swapo secretary-general Nangolo Mbumba, who holds a direct interest via his AMA Family Trust, according to an investigation into the N$7.4bn ($554m) expansion of Walvis Bay harbour.
