Over a decade ago, former President Mwai Kibaki called a press conference to declare that he had only one wife. This was in response to First Lady Lucy Kibaki's protest that the media was referring to Mary Wambui as Kibaki's second wife.
Kibaki (deceased) expressed his frustration after a former politician mentioned his rumoured relationship with Wambui on television. There were rumours that they had married under customary law dating back to the 1970s.
