President Pranab Mukherjee filed a caveat on Tuesday seeking a copy of the petition against him even before P A Sangma filed an election petition in the Supreme Court challenging Pranab Mukherjee's election as President .

The caveat was filed on behalf of Mukherjee by his advocate.

The Court Registry had also informed Sangma's lawyers at the time of his filing the election petition that a caveat has been filed on behalf of Mukherjee and copies of the necessary documents requested be served to his counsel.

News Agencies reported that Mukherjee's counsel confirmed the filing of caveat but refused to talk further.

Sangma had on Tuesday moved the Supreme Court challenging Mukherjee's election saying the veteran Congress leader was not eligible for the post as he was holding offices of profit at the time of filing his nomination for the top post.

The petition, filed by Sangma, has contended Mukherjee was holding the offices of profit as the chairman of Indian Statistical Institute (ISI), Kolkata, and was also the leader of Congress Party in Lok Sabha when he had entered the Presidential race.
