"I know my limitations. And I live and conduct myself according to my limitations." This was the response of finance minister P Chidambaram on Monday when asked to comment on DMK chief M Karunanidhi's remarks that he was potential prime ministerial candidate. "I don't know whether I should take your question very seriously. But let me give you a very serious answer. I know my limitations. And I live and conduct myself according to my limitations," he said.

On Sunday, Karunanidhi had supported a suggestion by actor Kamal Hassan that the finance minister was a potential prime ministerial candidate.

Chidambaram said if the reporters were expecting a light-hearted comment then "I tell you this: I know that some of you think I am foolish. But I am not so foolish as you think."
