"It is a politician's duty to maintain decorum when speaking in Parliament. It is shameful when they indulge in derogatory remarks about women," he tweeted without naming the JD (U) leader.
Stalin's tweet comes days after Yadav kicked up a controversy with his 'saanvli' remarks, referring to the colour of South Indian women, which created a furore.
Incidentally, DMK's Rajya Sabha member and Stalin's sister, Kanimozhi, had objected to Yadav's remarks on the floor of the upper house.
