The Congress has kicked off its Bharat Jodo Yatra (united India march) as part of which party MP Rahul Gandhi, other leaders and citizens will walk 3,500 km over the next 150 days from Kanyakumari to Kashmir valley, covering 12 states and two Union Territories. The march comes at a difficult time for the Congress, which has seen an exodus of senior leaders and continued confusion over who will lead the party next. The Aam Aadmi Party (AAP) has also launched its "Make India Number 1" programme from Haryana as it tries to expand its footprint. All of this is happening at a time when regional parties are trying to form some kind of opposition alliance to take on the BJP. Can a divided opposition unite?
