Rahul Gandhi has filed the nomination for the post of Congress president, paving the way for his much-awaited elevation ahead of 2019 Lok Sabha elections. 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. No application for nomination has been submitted so far. Rahul, who became Congress Vice-President in January 2013, will succeed his mother, who is the longest-serving chief of the party, having been at the helm from 1998.
