PM Modi's brief Manipur mention led to opposition walkout, unsatisfied with minimal focus in 2-hour speech.
Tensions rose as opposition left after 1 hour and 40 minutes without Manipur discussion.
Modi combined Manipur acknowledgment with criticism of opposition and Congress's historical role.
He stressed Northeast commitment, cited visits, blamed Congress politics, and highlighted disconnect.
Modi rejected accusations, challenged divisive language, referenced India's partition, and questioned unity commitment.
Speech ended with Modi invoking independence struggle, casting doubt on Congress's unity stance.
