However, his political career has always put him into unsavoury controversy.
Ghosh was a prominent figure during the 2009 Bengal Assembly elections when his scathing attack and harsh language against the incumbent CM Budhdhadeb Bhattacharya was specially noticed.
In 2012, Ghosh's educational qualification created quite a scene.
While Ghosh's highest academic qualification mentioned in his EC affidavit is just 'Madhyamik' (state secondary board exam, 1985), his Rajya Sabha profile states he pursued a certificate course (no specific year mentioned) in audio visual journalism, media management from Annex College of Management and Annex-Cygnus Institute of Management, Kolkata.
Incidentally, he was a board member of the institute.
