Former Congress MP Sushmita Dev, who resigned from the party on Monday morning, joined the All India Trinamool Congress today. Dev was the president of the Congress party’s women’s wing and had indicated her resignation from the party with a surprise change of her Twitter bio.

Confirming the development, the TMC said in a tweet, “We warmly welcome the former President of All India Mahila Congress Sushmita Dev to our Trinamool family!” The TMC also posted pictures of party national general secretary Abhishek Banerjee and Rajya Sabha MP Derek O’Brien welcoming Sushmita Dev to the party.

Sushmita Dev today quit the party and wrote a letter to chief Sonia Gandhi. The change in her Twitter bio to “Former Member” of the party was the first clue this morning that she has quit.

In her resignation letter to Congress president Sonia Gandhi, the former Assam MP is said to have written that she was beginning a “new chapter in my life of public service”. Dev had sent her resignation letter to Gandhi on Sunday, though senior Congress functionaries refuted the same even as they wished her well.

Dev was currently serving as a national spokesperson of the Congress and chief of the All-India Mahila Congress. Dev had offered no reason for her quitting the party.

Dev was among the Congress leaders whose Twitter handle was locked over a post showing images of the parents of a nine-year-old girl who was allegedly raped and murdered in Delhi.

As Rahul Gandhi’s account was blocked, several Congress leaders, including Ms Dev, changed their display picture to the Congress MP’s. The account was restored last week, after which the Congress posted “Satyameva Jayate”.
