The Congress on Tuesday won the Mandi Lok Sabha and all three Assembly seats in Himachal Pradesh where the bypolls were held on October 30, a setback for the ruling BJP, with CM Jai Ram Thakur saying the party will introspect.
The Mandi seat, which was earlier held by the BJP, was won by former chief minister Virbhadra Singh's wife Pratibha Singh.
She defeated BJP's Khushal Thakur, a Kargil war hero, by a margin of 7,490 votes.
Mandi is the home district of CM Thakur, who alleged that some BJP workers "operated" against the party candidates but said they will introspect.
The Congress retained Fatehpur and Arki Assembly seats while it wrested Jubbal-Kotkhai seat from the BJP, according to results announced by the Election Commission.
The BJP failed to save its deposit in Jubbal-Kotkhai.

In Mandi, Pratibha Singh got 3,69,565 votes against 3,62,075 secured by the BJP candidate.
