While the BJP said the party has become "stronger" with Sarma's induction, the Congress central leadership said it was monitoring the situation in Assam and was in touch with the state unit.

"I along with Assam BJP president Siddhartha Bhattacharya met BJP national president Amit Shah. We discussed a host of issues including the present political situation, floods etc. (in Assam)," Sarma told media persons outside Shah's residence in New Delhi on Sunday evening.

"I expressed my willingness to work under the strong leadership of Prime Minister Narendra Modi and national president Amit Shah and they have accepted it," he said.

"Perception of people changes with time and the same has happened to me. Since 2011, the debacle of the Congress had started in Assam and I conveyed it to Congress president Sonia Gandhi and (vice president) Rahul Gandhi. But nothing happened. Now I want to work with a strong leadership," Sarma added.

Sarma claimed he has the support of 52 Congress legislators out of 79.
