He added that the Congress intimidated its allies by putting the fear of the Central Bureau of Investigation (CBI) into them.
Addressing party workers at the SP headquarters in the state capital, Yadav - whose 22 MPs in the Lok Sabha are crucial for the survival of the Manmohan Singh led United Progressive Alliance (UPA) government - said that the Congress had "thousands of hands" which it uses to send its rivals behind bars.
"The union government has the CBI. It can get anyone arrested and jailed," Yadav added.
He also praised Jan Sangh founder Shyama Prasad Mukherjee.
"Mukherjee was a fighter and contributed greatly to the freedom struggle" he added.
Yadav had last month heaped praise on Bharatiya Janata Party (BJP) leader L.K. Advani and had vouched for the honesty of former prime minister Atal Behari Vajpayee.
Yadav has been under attack from Steel Minister Beni Prasad Verma and the Sp looked set to pull the rug from under the UPA's feet.
However, it stopped short after crisis managers from both parties worked overtime to ensure a ceasefire for the time being.
