Sources said most of the participants stressed on the need for concluding seat-sharing discussions at the earliest. Several leaders expressed apprehension about early polls. There was also suggestions that rallies should be held in different states, sources said.
The other agendas at the meet include choosing a logo for the alliance and setting up a coordination committee, sources had said. The alliance is also likely to hold discussions on whether to have a convenor or not and a joint action schedule for the 2024 elections.
