Describing the BJP leader as a "very nice man," Ramesh in his condolence message remembered the support Dave had extended to him during his stint as Environment Minister in the previous Congress-led UPA government.
"He supported whatever I did when I was minister," Ramesh said.
"He listened to everybody... (He) did not give offence to his political opponents," Ramesh said.
Sixty-year-old Dave complained of uneasiness at his home this morning and was rushed to AIIMS where he passed away, according to official sources.
He was a member of the Rajya Sabha since 2009.
