The introduction of the measure is part of a plan to widen revenue sources for the state broadcaster but critics say the licence fee is too high, especially given the difficult economic situation. Zimbabwe's President Emmerson Mnangagwa has signed into law a contentious bill that requires all motorists to buy a radio licence before acquiring vehicle insurance. The loss-making Zimbabwe Broadcasting Corporation (ZBC) relies for income on the licence fee as well as government grants, it also generates some revenue through advertising. Under the new Broadcasting Services Amendment Act, all motorists must now pay the radio licence fee before they can renew their vehicle insurance or obtain a licence from the Zimbabwe National Road Authority (Zinara). It prohibits all motor insurance companies from selling their products to motorists who do not hold a valid ZBC radio licence, unless they have a ZBC exemption certificate or the vehicle being insured does not have a radio receiver.
