Union Home Minister Amit Shah on Friday dubbed as a "photo session" the meeting of opposition leaders in Patna, and said their unity is nearly impossible and they will face drubbing in the next Lok Sabha polls. Addressing a public rally in Jammu, Mr Shah also slammed Congress leader Rahul Gandhi, saying he has the habit of criticising everything. Referring to the opposition meeting underway in Bihar's capital, Mr Shah said, "A photo session is happening in Patna. All the opposition leaders have come together on a single platform to convey a message that they will challenge BJP, NDA and Modi (in 2024).
