The misfortunes faced by the PKS have to some extent benefited the PAN, which has emerged as Mr Yudhoyono's most reliable coalition partner, with a pivotal position in the legislature. This alliance and the close personal relationship between Mr Yudhoyono and the PAN chairman, Hatta Rajasa, looks set to be strengthened further by the marriage of Mr Yudhoyono's youngest son, Edhie Baskoro Yudhoyono, who is commonly known as Ibas, and one of Mr Rajasa's daughters, Siti Ruby Aliya Rajasa. The marriage will unite two of the country's foremost political families. This suggests that Mr Rajasa, the co-ordinating minister for the economy, will become more influential within the government. Mr Rajasa and the PAN take an economic-nationalist stance on many issues and are less supportive of market-oriented reforms. The PAN chairman also has an indifferent track record on reform and clean governance, with questions raised over his performance as transport minister in 2004-07. His close relationship with Mr Yudhoyono may further diminish the influence of economic reformers within the cabinet.
