Amid concerns in the party over leadership issue and calls for elections to the top post, the Congress on Thursday said Rahul Gandhi was a clear successor for party president’s post to his mother and incumbent Sonia Gandhi. With differing voices emerging within the party over the leadership issue, a senior Congress leader claimed that Rahul has acceptability across the country and also the capability to lead the party. Congress sources said Rahul was the only contender in the race for the president’s post because the entire rank and file of the party want him to lead, hinting that elections in that case may not even be necessary.There is also speculation that Rahul may be elevated to the top post in the proposed plenary session of the Congress slated sometime in April. Sources in the party said that the session may be slated after the budget session of Parliament and a major section within the party wants Rahul to be installed as party president again. Congress leaders Sandeep Dikshit and Shashi Tharoor have made calls for fresh elections for the party’s top post to infuse fresh vigour in the party.
