Pragatisheel Samajwadi Party (Lohiya) chief Shivpal Singh Yadav on Friday celebrated birthday of his brother Mulayam Singh Yadav.
He also cut the cake and organised wrestling competition in Etawah's Saifai.
Shivpal, who quit Samajwadi Party to float his own party, said he did not want to contest Lok Sabha election from Firozabad seat which he lost to a BJP candidate.
"People said my party is new and I will not get more than 500 votes that is why I contested election from Firozabad," he said.
