New Delhi: Under attack for sexist remarks, JD(U) leader Sharad Yadav on Monday remained unapologetic for his comments on women's 'dark-skinned complexion', as he raked it up again saying he was ready for a debate on the issue.

"I said 'saanvli' (dark-complexioned) women are more in number in India, they are more in number also the world over. I am ready to debate with anyone on the struggle of (Ram Manohar) Lohia and others for these women," he said in Rajya Sabha.

As Yadav explained his position on the issue, he was interrupted by both treasury and opposition members including HRD Minister Smriti Irani.

"I appeal to the gentleman (Yadav) not to make comments on the colour of skin of women in this manner. A very wrong message is going out," she said.

As other MPs joined in, Deputy Chairman P J Kurien said he would not allow a discussion on the issue. "I am not allowing any discussion, white or dark colour, it is all the same," he said.

The issue figured after Telecom Minister Ravi Shankar Prasad rose to dissociate himself from comments made by Yadav last week. "I completely disassociate and disapprove of the remarks. I appeal to Sharad Yadav to kindly withdraw his comments," he said.
