NEW DELHI, Jan. 15 -- The process to elect the Bharatiya Janata Party's (BJP) new national president is set to begin this weekend with a formal notification outlining the election schedule, followed by the filing of nominations, the scrutiny of papers, and the eventual declaration of results, people aware of the matter said. According to people familiar with the development, the official announcement of the new party president is expected on January 20, when current working president Nitin Nabin is set to be elected to the role, succeeding JP Nadda. Nadda was also first appointed as working president in 2020 before formally taking the helm a year later. Since it is expected to be an unopposed election, Nabin's elevation is almost certain. "...
