The counting of votes polled in the November 9 by- election began at around 8 am amid tight security.
Chaturvedi was leading by 6,000 votes over Tripathi at the end of the third round of counting, an election official said.
Around 65 per cent voting was recorded in the bypoll necessitated following the death of sitting Congress MLA Prem Singh (65).
Singh had won the assembly constituency, bordering Uttar Pradesh, in the 1998, 2003 and 2013 elections.
Though 12 candidates contested the by-election, the main fight was between Chaturvedi and Tripathi.
