After attending the Pakistan Day reception in New Delhi yesterday, Union minister and former army chief General V K Singh tweeted of "disgust" and "duty".

The tweets are being seen as a rebellion by Singh. He later clarified, "Disgusted to see how certain sections of the media are twisting this issue."

On Facebook page, he posted some definitions as per Collins dictionary of "disgust" and "duty" and listed the meanings as tweeted by him.

But as the controversy snowballed, Congress' Manish Tewari said that Singh should step down. "If Mr#duty#Disgust is so disgusted with double standards of his govt on Pak he should quit? Other Min in past refused to attend PAK EVENTS," Tewari tweeted this morning.  

In response, BJP's Subramaniam Swamy asked, "Why does Congress want V K Singh to quit?"

Sources said that Singh had been deputed to the event after clearance from the prime minister.

The Pakistan Day reception is an annual diplomatic event but it generated a controversy because of the presence of the separatist leaders.
