On 4 December 2005, new presidential elections were held where Nazarbayev won by an overwhelming majority of 91.15% (from a total of 6,871,571 eligible participating voters). Nazarbayev was sworn in for another seven-year term on 11 January 2006. In 2009, former UK Cabinet Minister Jonathan Aitken released a biography of the Kazakh leader entitled "Nazarbayev and the Making of Kazakhstan". The book takes a generally pro-Nazarbayev stance, asserting in the introduction that he is mostly responsible for the success of modern Kazakhstan.
