Health Minister Harsh Vardhan on Thursday said that he has always maintained transparency in his 25-year long political career and he does not need anyone's certificate.

"I have not seen the notice of the Delhi High Court yet. I have seen only the news on television. I will give my version to the court after reading the notice but I would like to say that I have always maintained transparency in my 25-year long career and I do not need anyone's certificate," he said responding to an election petition filed against him in the Delhi High Court.
