Congress has won the Mandalgarh assembly byelection in Rajasthan and is leading in the two Parliamentary seats of Ajmer and Alwar.

This is turning out to be a massive blow to the Vasundhara Raje-led BJP government in Rajasthan that is headed for assembly elections in a few months.

In Rajasthan, the by-polls are not only a test for Chief Minister Raje, but also for Rajasthan Congress chief Sachin Pilot, who has been campaigning aggressively in Alwar and Ajmer.

These five constituencies went to polls on January 29.(Agencies)
