Bharatiya Janata Party (BJP) president Rajnath Singh, who is all set to get another term as party chief, will file his nomination papers for the post on Sunday.
"Singh will file his nomination papers at the party headquarters in New Delhi in the presence of senior party leaders Atal Bihari Vajpayee and LK Advani," a BJP leader said.
"According to the party's constitution, Singh's current term will end in December. Now he will be elected for a three-year term," he added.
Singh was nominated to the post of BJP president after former deputy prime minister Advani quit the post in December last year before completing his term.
"Singh is likely to be elected unopposed to this post. No other leader is going to file nomination. His election is a mere formality," the leader said.
Singh, who belongs to Uttar Pradesh, entered politics in 1974. In October 2000 he became CM of Uttar Pradesh. In 2003 he was appointed as union minister of agriculture. In July 2004, he was nominated as BJP's national general secretary.
