He dismissed the reports as "baseless". "In some sections of the press/media, it has appeared that I would be contesting a by-election from any of the Gorakhpur, Phulpur and Alwar Lok Sabha Seats which have fallen vacant," he said in a statement.
But the former Member of Parliament said there was no truth in the reports.
"There is no truth (in this) and (the news is) completely baseless. I have no plans of contesting any by-election for the above mentioned Lok Sabha seats," Mr Yadav said in the statement.
The Gorakhpur and Phulpur seats in UP fell vacant after Uttar Pradesh Chief Minister Yogi Adityanath and Deputy Chief Minister Keshav Prasad Maurya became members of the UP legislative Council.
The death of BJP's sitting MP Mahant Chandnath in September led to a vacancy in Alwar, Rajasthan.
