Mumbai Congress chief Sanjay Nirupam Friday slammed Lok Sabha Speaker Sumitra Mahajan over her comments on Rahul Gandhi's leadership qualities and said she was "unfit" to occupy the Constitutional post.

"Sumitra Mahajan's comments prove she is not fit to occupy the Constitutional post. She has no right to continue as the speaker. Her comments denigrate the august office of speaker of Lok Sabha," Nirupam said.
