Sukhbir Singh Badal won from Firozpur and his wife, a two-time MP from Bathinda, retained her seat. Both the constituencies are considered SAD strongholds.
“I want to thank… the people of Punjab,” Sukhbir told reporters.
The SAD president said with his party winning two seats, the Congress’s “Mission 13” has completely failed.
He said it showed that “those who used to make statements against the Badal family were actually spreading false propaganda”.
Sukhbir defeated SAD rebel and Congress candidate Sher Singh Ghubaya with a handsome margin of over 1.98 lakh votes, according to the Election Commission.
Sukhbir led from the front at a time when his party was facing criticism from political opponents over desecration of religious scriptures. His party had been under fire over the 2015 sacrilege and police firing incidents in which two persons were killed.
The former deputy chief minister of Punjab, who is the Jalalabad MLA, took the plunge in the Lok Sabha polls after a gap of 15 years to revive his party’s fortunes.
The SAD, which dominated state politics for decades, was relegated to the third spot in the 2017 assembly polls as it won only 15 of the 117 seats.
In Bathinda, it was a high-stakes battle for the SAD, with Harsimrat seeking re-election for the third time.
Harsimrat defeated Warring by a margin of 21,772 votes, the EC data showed.
She even bettered her victory margin this time as against 19,395 votes in 2014 Lok Sabha polls.
Harsimrat also thanked the voters for her victory.
However, the SAD did not have any luck in the remaining eight constituencies despite the party fielding old warhorses like Jagir Kaur (Khadoor Sahib), Gulzar Singh Ranike (Faridkot), Charanjit Singh Atwal (Jalandhar), Prem Singh Chandumajra (Anandpur Sahib) and Parminder Singh Dhindsa (Sangrur) in some of them.
