Background information
Lesotho, as a former British colony, adopted the pre-1950s UK standard: types D & M. Originally, there were four plug and socket versions: 2 A, 5 A (=type D), 15 A (=type M) and 30 A. Lesotho initially standardized on both the 5 amperes plug (type D) and the 15 amperes plug (type M), but in the end only type M remained.
