Tharoor, who has been allocated the portfolio of Minister of State in the HRD Ministry, is expected to take charge soon.
"It is very unfair to comment on persons who is as experienced as Shashi Tharoor. You must all remember that he has held important positions in the United Nation and is a scholar and a man of great distinction.
"We think, we should utilise his skill in this Ministry that touches so many lives," Raju told reporters here when his attention was drawn to Naqvi's remarks.
Naqvi had reportedly termed him a "love guru" while taking a jibe at the newly-appointed minister over his comment against Gujarat Chief Minister Narendra Modi yesterday.
Tharoor had tweeted, "My wife is worth a lot more than your imaginary 50 crores. She is priceless."
