The Rajasthan BJP had lodged a complaint in the matter.
The Chief Electoral Office in Rajasthan has written to the Election Commission of India (ECI) demanding further action into the matter of Loktantrik Janata Dal leader Sharad Yadav allegedly insulting former chief minister Vasundhara Raje.
In an election rally in Alwar, Mr Yadav had allegedly said that Ms Raje had become fat and needed rest. A video of Mr Yadav's alleged comments was viral on social media.
"I feel insulted. This is an insult to women. I am absolutely shocked because I did not think any experienced leader and one who had close ties with our family could not control his language," Ms Raje said.
