Most notorious of a raft of graft scandals was the multi-billion shilling Anglo Leasing case, which emerged in 2004 and involved public cash being paid to a complicated web of foreign companies for a range of services—including naval ships and passports—that never materialised." However, the passage of Kenya's transformative 2010 Constitution, successfully championed by President Kibaki in the Kenyan constitutional referendum in 2010 was a major triumph and achievement, which went a long way into addressing Kenya's governance and institutional challenges. With the new Constitution started wide-ranging institutional and legislative reforms, which President Kibaki skilfully and successfully steered in the final years of this presidency."His greatest moment was the promulgation of the new Constitution... It was a very deep and emotional moment for him," Kibaki's son Jimmy was quoted as saying. A proud looking but rather worn President Kibaki handed over the Kenyan presidency to his successor, Uhuru Kenyatta, on 9 April 2013 at a public inauguration ceremony held at Kenya's largest stadium. "I am happy to pass the torch of leadership to the new generation of leaders", said Kibaki. He also thanked his family and all Kenyans for the support they had given him throughout his tenure in office, and cited the various achievements his government made. The handover marked the end of his presidency and of his 50 years of public service. President Kibaki was married to Lucy Muthoni from 1961 until her death in 2016. They have four children: Judy Wanjiku, Jimmy Kibaki, David Kagai, and Tony Githinji. They also have several grandchildren: Joy Jamie Marie, Rachael Muthoni,Mwai Junior and Krystinaa Muthoni. Jimmy Kibaki did have, so far unsuccessful, designs to be his father's political heir. In 2004, the media reported that Kibaki has a second spouse, whom he allegedly married under customary law, Mary Wambui, and a daughter, Wangui Mwai. State House in response released an unsigned statement that Kibaki's only immediate family at the time was his then wife, Lucy, and their four children. In 2009, Kibaki, with Lucy in close attendance, held an odd press conference to re-state publicly that he only has one wife. The matter of Kibaki's alleged mistress, and his wife's usually dramatic public reactions thereto, provided an embarrassing side-show during his presidency, with the "Washington Post" terming the entire scandal as a "new Kenyan soap opera".
