Reminiscencing, Philipose said Bidwai was "a concerned human being...concerned journalist who worked for voiceless in the country" and had a "great mind".

"He understood politics of the world very well, and was a realistic journalist. His work with various media organisations speaks for itself," she said, adding that Bidwai also had a solid academic background which worked in his favour as a journalist.
