"I was disinclined" to move to the Home Ministry but in a situation like this, "I answered to the call of duty", P Chidambaram said on Monday on his portfolio being changed from Finance Minister to Home Minister.

"When the Prime Minister conveyed the decision to me, I will be less than honest if I do not say that I was disinclined," Chidambaram told reporters while winding up his duties with the Finance Ministry.

"But in a situation like the one we find ourselves, the final call is taken by the party leader, in my case the Congress president and the Prime Minister. I therefore answered to the call of duty," he said.
