Photograph: Eraldo Peres/AP The late Nigerian president Umaru Yar'Adua had a kidney transplant in 2002 while he was a state governor, but avoided having another one while he was president over fears it would cause unrest, according to diplomatic cables released by WikiLeaks. The cables suggest power brokers in the ruling People's Democratic party knew about Yar'Adua's condition, but propped him up to become the winning presidential candidate in 2007. Aides to the president stuffed his clothes to hide his weight loss and used makeup to hide his pallor, the cables claim, but his illness ultimately led to a long absence from the oil-rich nation that fuelled public discontent. Yar'Adua died in May 2010, propelling the vice president Goodluck Jonathan into the presidency. Jonathan is the ruling party's presidential candidate for the April election, upsetting a balance of power between the nation's Christian south and Muslim north. "What is clear is that the president's health is a matter of growing concern, particularly on the minds of the northern Nigerian elite," a diplomatic cable from February 2009 reads. "We have noted a considerable uptick in what appears to be behind-the-scenes machinations and back-room dealing." WikiLeaks publicly released the cables on Saturday night. A spokesman at the US Embassy in Abuja, Nigeria's capital, has said officials would have no comment on anything released by the website. A diplomatic cable from June 2008 claims Yar'Adua first began experiencing renal failure in 1999, just as he became governor of the northern state of Katsina. The cable says German company Julius Berger, one of the dominant road construction firms in Nigeria, set up a dialysis clinic in Yar'Adua's home. The firm later would fly German experts in and out of Nigeria to privately treat Yar'Adua, the cables claim. The cables claim Yar'Adua received the transplant in 2002 from donor Sayyadi Abba Ruma, who would serve as minister of agriculture and water resources when Yar'Adua came into power. Ruma denied the cable claim, calling WikiLeaks a "witch-hunting device" and "a strategy for blackmail." "It never happened," Ruma told Associated Press tonight . "It's not true. It's malicious. It's mischievous." The discolourations long noticed on Yar'Adua's face, fuelling rumours about his ill health, came from the steroids doctors gave him to help his body accept the transplant, according to the cables. Yar'Adua became president in 2007 through an election international observers described as rigged. His health continued to fail. Doctors apparently told Yar'Adua he needed a second transplant and Ruma's brother was sent to Germany to be checked as a possible donor, according to the cable. However, a planned trip was put on hold over political calculations. "Yar'Adua did not take this planned trip given public reaction to rumours about travel and concerns about his ability to govern," the February cable reads. "We have no information on whether this trip may be rescheduled." The president's health continued to worsen. Yar'Adua left Nigeria on 23 November 2009, to seek medical treatment in Saudi Arabia. His physician later told journalists Yar'Adua suffered from acute pericarditis, an inflammation of the sac surrounding the heart. However, Yar'Adua's stay in Saudi Arabia drifted from days to weeks to months, stalling government activity in a nation vital to US oil supplies. Yar'Adua returned to Nigeria in late February 2010, but never appeared publicly. He died 5 May. Jonathan now faces minor party candidates from across the north in the 9 April presidential election.
