[3][4] Sidhu entered political arena in 2019, campaigning for the BJP candidate Sunny Deol, and later trying to take a leading role in the 2020-2021 farmers' protest.

[5] A few months before his death in a road accident, he founded a Punjabi Sikh organisation Waris Punjab De.

[6][7][8][9] Deep Sidhu was born on 2 April 1984[10][11] (or 1979, per his driving licence),[12] to a Punjabi family in Udekaran village of Muktsar district of Punjab.

He rose to greater prominence with Jora 10 Numbaria (2017), in which he played the lead role of a gangster, making him a star.

[24] Sidhu entered the political sphere during the 2019 Indian general election when he campaigned for the actor-turned-politician Sunny Deol, who was the BJP candidate for the Gurdaspur constituency.

[13] Throughout this period Sidhu was firm in his position that the protests were not merely about the farm bills, but to "change the entire power equation".

[27] At one stage, one of the protesting youth raised pro-Khalistan slogans, and the morcha manager Hakam Singh handed him over to the police.

For the Republic Day on 26 January 2021, the farmer unions planned a "Kisan Parade" on tractors through the Outer Ring Road, along a route agreed upon with the police.

[37][38] After a preliminary investigation, they concluded that "there was a pre-conceived and well-coordinated plan to break the agreement between the Delhi Police and the leaders of protesting organisations.

"[39][40] Sidhu was arrested on 9 February 2021 from Karnal in Haryana on charge of instigating farmers to storm the Red Fort and causing violence.

[43] After his bail plea was approved, he was arrested a second time on a police case filed by the Archaeological Survey of India (ASI).

[46] In September 2021, Sidhu formed a political organisation named Waris Punjab De, that aimed to get more rights for farmers from the Union government.

[47] Before his death, he gave support to[48] the pro-Khalistan leader Simranjit Singh Mann and Shiromani Akali Dal (Amritsar).

[49][50] According to Sonipat police, Sidhu died around 9 P.M. near the Peepli toll booth, after his car hit the rear end of a truck parked on the highway.
