His both sons are also married. His elder son and the present Chief Minister of Uttar Pradesh, Akhilesh Yadav got married to Dimple Yadav in 1999, who is also a politician and has three children.
His younger and "lessor-known" son, Prateek, who is into real-estate business, is married to his "childhood girlfriend" Aparna Bisht, since 2011.
In his initial days, Mulayam also worked as a lecturer and a wrestler!

Performance as Samajwadi Party supremo: The veteran politician, Mulayam has been at the helm of all the crucial affairs of the SP, even though his son Akhilesh Yadav is the Chief Minister of UP since 2012.
One of the key players of the Indian politics, Mulayam "calls the shots" and claims to be one of the most important players in the 'Third Front' formation.
Interesting facts about Mulayam Singh Yadav: There was a time when Mulayam borrowed a cycle to travel in the countryside where he was born and bred.
He is diminutive but a "never say die fighter" and has proved why he cannot be vanquished in his home turf. His indomitable energy and ability to mix with ordinary folks quickly won him numerous admirers.
Aides recount tales of Mulayam stopping by roadside eateries to chat with commoners.
Mulayam draws support dominantly from the Yadav clan and Muslims. His political hub is the backward belt of Mainpuri and Etawah, the former home to a thriving industry in locally-made guns called 'katta'.
Loyalty means a lot to him.
He has retained his Personal Security Officer Shiv Kumar, his personal secretary Jagjivan and telephone operator-cum-attendant Tara Chand for the last three decades.
While he largely remains a socialist at heart, his lifestyle changed midway. For one who used to sip butter milk bottled in a thermos flask during flights, he now prefers ginger ale.
