Visakhapatnam: "I am not a mad man. I am a realist and I know my limitations," was how Defence Minister AK Antony reacted when asked whether he was a candidate for the Presidential elections.

"There should be a limit to ambition. That is madness," he said, virtually ruling himself out of the race for elections in July when the tenure of President Pratibha Patil ends.

No names for Patil's successor have emerged yet.
