Opposition leaders used the occasion of a book launch on Kharge's completion of 50 years in electoral politics to assert that the Congress president should lead all opposition parties together so that they can win the 2024 elections. DMK's T R Baalu, CPI-M leader Sitaram Yechury and RJD MP Manoj Kumar Jha were among those who hailed Kharge's leadership and called upon the opposition parties to give up their differences.
