Reacting to the departure of former spokesperson Sushmita Dev, Congress leader K C Venugopal told news agency ANI "it is not an issue for Congress if somebody is going or coming."
"So many people have joined Congress but you are not talking about that. We are a strong party," he added.
Sushmita Dev on Monday in a letter addressed to Sonia Gandhi announced her resignation from the Congress Party and joined the Trinamool Congress (TMC) in Kolkata.
