New Delhi: Rahul Gandhi will file his nomination papers for the election to the Congress president's post today.

He will be accompanied by a host of senior leaders including Sonia Gandhi and former prime minister Manmohan Singh.

Rahul Gandhi is likely to emerge as the lone candidate in the fray and decks have been cleared for his election as the Congress president, succeeding his mother Sonia Gandhi, who has held the post for 19 years in a row now.

Rahul Gandhi will file four sets of nomination papers. Senior party leaders Sonia Gandhi, Manmohan Singh, Ghulam Nabi Azad, A K Antony and Ahmed Patel and party chief ministers will sign the papers as proposers.

Congress delegates from various states will be at the party's headquarters on Akbar Road today filing their sets of nomination papers proposing Rahul Gandhi's name for the top post.

Congress communications in-charge Randeep Surjewala said all party general secretaries and CWC members, besides states and frontal organisations will file nomination forms in Rahul Gandhi's favour.

Party spokesperson Sushmita Dev said Rahul Gandhi will officially file his nomination papers today.

Asked about criticism of the party's internal polls, she said, "There has been criticism on whether the Congress election is democratic or not. I would say that this is such an election which is being supervised by the Election Commission of India." 

Dev said when one talks about electoral democracy, here is full transparency in these polls as they are held as per rules prescribed by the Election Commission.

Punjab Chief Minister Amarinder Singh, who will be present today, wished Rahul Gandhi success and said his elevation was a "good sign for the party".

"It is a good sign for the party and I'm sure he'll do extremely well," he said.

Singh said he was very happy to see him at this position as "I have known Rahul since he was a little boy and I knew and could see it in him that he would one day rise to the top." 

"He has already performed and for the last few days we have been following him and the way he is drawing crowds in Gujarat," the Punjab chief minister added.
