All India Mahila Congress chief Sushmita Dev resigned from the Party on Sunday, 15 August. She joined the All India Trinamool Congress in the presence of party leaders Abhishek Banerjee and Derek O'Brien on Monday.
She announced her resignation in a short letter to Congress interim president Sonia Gandhi.
"Please treat this as my resignation from the primary membership of the Indian National Congress. I cherish my three-decades long association with the Indian National Congress. May I take this opportunity to thank the Party, all its leaders, members and workers who have been part of my memorable journey," she wrote in her letter.
"Madam, I thank you personally for your guidance and the opportunities you gave me," she further added.
Dev's exit has surprised many in the Congress as she was known to be a staunch Rahul Gandhi loyalist. She was extremely proactive as the head of the Mahila Congress and led a number of protests on women's issues.
