Speaking on condition of anonymity, a senior Congress leader said that Ramesh wrote to Singh and Gandhi after he was reprimanded by the Prime Minister for speaking against the government's policy against China in an international forum.
His remarks drew the ire of other party members too.
"Congress wants to make it clear that commenting on departments that are not in a minister's domain is not at all appropriate. It should not be done under any circumstances on foreign soil," party spokesperson Abhishek Manu Singhvi had said.
The BJP too joined in slamming the Environment Minister, calling his behavior as unbecoming of minister and added that the party would demand his resignation if the Prime Minister fails to take action against him.
Ramesh, known for his controversial remarks, found himself in a tight spot when he spoke against the government policy in Beijing during a global meet on climate change on Saturday, May 9.
He said that the Home Ministry was 'alarmist and paranoid' in its approach towards entry of Chinese companies in India.
