"I dare the Congress party to announce that they want to make Ahmed Patel the chief minister of Gujarat," Modi told an election rally in Maninagar.
The poll fight heated up today with the Congress fielding Shweta Bhatt, the wife of suspended IPS officer Sanjeev Bhatt, against Modi from the Maninagar constituency.
"My fight is to re-establish democracy in Gujarat," Shweta Bhatt told reporters after filing her nomination papers.
This is the second instance where the spouse of crucial Modi critics have taken the poll path.
Jagruti Pandya, wife of slain Gujarat home minister Haren Pandya, is also fighting the polls on a Gujarat Parivartan Party ticket from Ellis Nagar constituency in Ahmedabad.
The state is voting on 13 and 17 December. The counting is scheduled on 20 December.
