- BJP lawmaker has criticised his party over a range of issues in the past
- Mr Sinha questioned PM Modi's, Amitabh Bachchan's silence on "Padmavati"
- "...someone else has a patent for Mann Ki Baat," Mr Sinha said
Mr Sinha, who seemed to be taking a swipe at those in his own party who are not in good terms with him, said he too can speak on the economy if other people can do so without being a specialist.
"If vakeel babu can speak on finance, if a TV actress can become the country's HRD minister and if a chai wala can become... I wouldn't say any further... Why can't I speak on economy?" said the BJP leader who has criticised his party over a range of issues in the past. On Wednesday, Mr Sinha in a tweet had questioned PM Modi and Bollywood actor Amitabh Bachchan's silence amid relentless protests over the release of the movie Padmavati.
When he was a child, PM Modi used to help his father sell tea at a railway station in Vadnagar in east Gujarat. In October, when the Prime Minister visited Vadnagar -- his first since 2014 when he took over the top job in the country -- the dilapidated tea kiosk was spruced up and decked up with flowers.
Mr Sinha said people have asked him what qualification he has to speak on the economy as his career has its roots in the film industry.
"If I do not speak for the youth, for the poor... for the oppressed, then what am I doing in politics?" Mr Sinha said.
"I am speaking from my heart though it is not mann ki baat because someone else has a patent for mann ki baat," Mr Sinha said at the book launch. "Some people say I speak against my own government's policies because I was not made a minister. To be honest, I neither have any desire nor any expectation to become a minister," he added.
