"Ganesan was the only candidate, who had filed nomination for the lone vacant seat for the Rajya Sabha by-poll in the state," Returning Officer and Madhya Pradesh Assembly's Principal Secretary, A P Singh, told PTI.
He was declared elected unopposed to the Upper House on the last day of the withdrawal of nominations today, he said.
The result was announced in the presence of Ganesan and Alok Sanjar, BJP MP from Bhopal.
The seat had fallen vacant after former union minister Najma Heptulla resigned from it on August 20 following her appointment as Governor of Manipur. The by-election was necessitated as the tenure of her seat is till April 2, 2018.
