Kaur, wife of former chief minister Amarinder Singh, won by a margin of over 23,282 votes, an election office spokesman said.

The seat fell vacant after Amarinder got elected to Lok Sabha from Amritsar. Patiala seat was retained by Congress.

Kaur polled 52,967 votes, SAD nominee Bhagwan Dass Juneja 29,685 and Aam Aadmi Party (AAP) candidate Harjit S Adaltiwala 5724 votes.

Soon after the declaration of results, Kaur told reporters that "I will fight for the development of Patiala in the assembly and will make strategy to form Congress Government in state in next assembly elections."

Meanwhile, SAD candidate's son Gurpal Juneja died of heart stroke on Sunday night, his family said.

AAP, which had bagged four Lok Sabha seats out of total 13 in Punjab, had finished third at Patiala whereas its candidate Baljinder Kaur is trailing way behind SAD and Congress candidate from Talwandi Sabo seat.

Before falling vacant, both Patiala and Talwandi Sabo seats were with Congress.

Sidhu polled 71,747 votes, Jassi got 25,105 votes, AAP's Baljinder Kaur 13,899 and Independent Balkar Singh 6,305 votes.
