"Mulayam Singh Yadav marked his ballot paper in favour of Sangma and then realising his mistake tore it and requested the Returning Officer to give him another ballot paper, who issued another ballot paper to him. We have objected to the tearing of first ballot paper and objected to him being given another ballot paper, which he is not entitled to," Jain said in his complaint.
The Sangma camp has sought cancellation of the second ballot paper issued to him and demanded that the first vote marked by him be considered valid.
Jain has also handed over a copy of his complaint to the election observers.
He said, "Fortunately the first ballot paper has been preserved under a sealed cover with the Returning officer".
Yadav, who backed UPA Presidential nominee Pranab Mukherjee, on Thursday mistakenly cast his vote in favour of BJP-backed PA Sangma, but took remedial steps and requested for another ballot paper which was given to him.
The SP had backed Mukherjee after giving the ruling UPA some anxious moments as Yadav had initially teamed up with Trinamool Congress chief Mamata Banerjee and proposed the names of Prime Minister Manmohan Singh, former Speaker Somnath Chatterjee and former President APJ Abdul Kalam as possible candidates for the 14th Presidential election. He later announced his support to Mukherjee.
