A major factor in favour of Advani was that he had always been the most powerful leader in the BJP with the exception of Vajpayee, who endorsed Advani's candidacy. On 2 May 2007, BJP President Rajnath Singh stated that: "After Atal there is only Advani. Advani is the natural choice. It is he who should be PM". On 10 December 2007, the Parliamentary Board of BJP formally announced that L. K. Advani would be its prime ministerial candidate for the general elections due in 2009.
