The relationship between Advani and the RSS reached a low point when the latter's chief K. S. Sudarshan opined that both Advani and Vajpayee give way to new leaders. At the Silver Jubilee celebrations of the BJP in Mumbai in December 2005, Advani stepped down as party president and Rajnath Singh, a relatively junior politician from the state of Uttar Pradesh was elected in his place. In March 2006, following a bomb blast at a Hindu shrine at Varanasi, Advani undertook a "Bharat Suraksha Yatra" (Sojourn for National Security), to highlight the alleged failure of the ruling United Progressive Alliance in combating terrorism.
