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. He was said to have been close to Deol and his pictures with Deol and prime minister
Narendra Modi got circulated later in 2020.
Farmers' protest When
farmers' protests began in Punjab in late 2020, against the
BJP government's
farm laws, the artistes of Punjab were prodded on social media into supporting the protests. Deep Sidhu organised a protest at
Shambu on Punjab–Haryana border on 25 September, along with a former gangster called Lakha Sidhana, which came to be called the "Shambu Morcha". The artist-organised protests did not meet with the approval of the farmer unions, who saw them as upstaging their own protests. They also said that these protests were misguiding the youth. Moreover, Sidhu and Sidhana were asking the protesters to broaden the agenda beyond the farm bills into a general protest against the Union government, in opposition to an alleged "attack on Punjab". Sidhu also rebuffed the objections of the farmer unions saying that he would not abide by directives that were issued from closed-door meetings. until, in collaboration with Bharatiya Kisan Union (Sidhupur), the morcha broke the barricades at the Shambu barrier and marched towards Delhi. This forced the other unions also to march to Delhi. They had to be seen in the context of the "federal structure and existence of Punjab". His Shambu Morcha, which is said to have been independent of the farmer unions, was live streamed by pro-Khalistan channels. During the parade, some farmers that bought into the idea diverted from the agreed route, entered central Delhi near the
ITO metro station, broke the police barricades and clashed with the police. There was rioting. In the afternoon, they entered the
Red Fort area in their tractors, climbed on the ramparts of the monument and hoisted flags. Deep Sidhu was among them. According to
IANS, Sidhu did a Facebook Live broadcast of the event and commented, "We have only hoisted the
Nishan Sahib flag (Sikh religious flag) on the Red Fort while exercising our democratic right to protest." The federation of the farmers' unions,
Samyukt Kisan Morcha distanced itself from Sidhu and accused him of leading the farmers to the Red Fort. The Delhi Police booked Sidhu and Sadhana for instigating violence at the Red Fort. 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." Sidhu was arrested on 9 February 2021 from
Karnal in Haryana on charge of instigating farmers to storm the Red Fort and causing violence. He pleaded innocence and claimed he was not involved in any violence nor incited others. He said that he had exercised his right to peaceful protest and was implicated as he was a "popular face" present "at the wrong place at the wrong time". After his bail plea was approved, he was arrested a second time on a police case filed by the Archaeological Survey of India (ASI). ASI had accused Sidhu of damaging the monument and vandalism by the rioters. His lawyer denounced the second arrest after bail as unconstitutional. He was released on bail on 16 April 2021.
Waris Punjab De In September 2021, Sidhu formed a political organisation named
Waris Punjab De, that aimed to get more rights for farmers from the Union government. Before his death, he gave support to the
pro-Khalistan leader
Simranjit Singh Mann and
Shiromani Akali Dal (Amritsar). ==Death==
