Shivpal Yadav, Samajwadi Party chief Mulayam Singh Yadav's favourite younger brother now rebelling, staged a show of strength on Friday morning outside his Lucknow home, where his supporters have gathered and are shouting slogans. "I am with Netaji... don't let the party weaken," Shivpal Yadav told his supporters urging them to meet the party chief at the Lucknow office today, using the name that family and the party use to address Mulayam Singh.
