Former Lok Sabha speaker P A Sangma said he was returning to the Nationalist Congress Party.
"I left NCP due to disagreement on the issue of Sonia Gandhi becoming the prime minister. But she refused to be PM and vindicated my stand. Now differences do not exist", Sangma told reporters at the NCP headquarters in Guwahati on Wednesday.
On his rejoining the NCP instead of the Congress, Sangma said, "I had joined the Congress 30 years ago, but I have an emotional attachment to the NCP as I founded it with Sharad Pawar and Tariq Anwar, gave its name, wrote its constitution and even prepared its vision document".
"As the difference no longer exists and people need a third front, I decided to return to NCP to strengthen it," he said.
Asked if he would rejoin the Congress if invited to do so, he said, "There is no need to and no question of going back. The NCP has its own identity."
Sangma, who won the last elections as a Trinamool Congress candidate, said, "I am waiting for an appropriate time to resign to formally rejoin NCP."
