The BJP headquarters in New Delhi have issued a letter to ex- West Bengal BJP chief Dilip Ghosh cautioning him against making comments that could harm the party;s interest, reports ndtv.com.

In April, the now National Vice President of BJP, had publicly slammed his successor Sukanta Majumdar's way of functioning in the state. The saffron party performed far behind expectations in the state assembly polls.

"Sukanta Majumdar is less experienced. The party has been fighting for long and there are experienced veterans...They should be put up to fight in the state," Ghosh had said.

In the letter signed by BJP headquarters in-charge Arun Singh, the party "reminded the Bengal leader that he had been told to guard against making controversial comments in the past too, "in the fond hope that you will take note."

Ghosh, the letter shows, has not taken note of the party's previous advice yet.

"In [a] recent interview, your comments in the electronic media and perhaps on other forums have been openly critical of senior state functionaries. Such comments will only hurt and harm the party and negate your own hard work in the past," the BJP said in the letter to Ghosh.

"While your commitment to the party has been absolute, there have been some avoidable instances when some of your statements or outbursts have anguished the state party leaders and have also caused embarrassment to the central leadership," the letter said.

"The national leadership of the BJP is deeply concerned at the issuance of such statements through the media...On the instructions of National [party] President Shri JP Nadda ji, I wish to convey to you the party's deep anguish...I sincerely hope you would appreciate the sensitivity of the situation, particularly in West Bengal, and shall always remain more discreet in your dealings with the...media or any public fora," the letter read.
