As a student

Khurana had his training in politics at Allahabad University, where he was doing his post-graduation in economics.^[6] He was general secretary of the Allahabad Students Union in 1959 and became general secretary of the Akhil Bharatiya Vidyarthi Parishad in 1960.^[8]

Jan Sangh

As a youth, Khurana became a teacher with Vijay Kumar Malhotra, at PGDAV (evening) College before deciding to enter politics.^[6] Madan Lal Khurana, Vijay Kumar Malhotra, Kedar Nath Sahani and Kanwar Lal Gupta founded the Delhi chapter of the Jan Sangh, which in 1980 transformed into BJP. Khurana was the Jan Sangh's general secretary from 1965 to 1967. He dominated first Municipal Corporation politics and then the Metropolitan Council where he was the Chief Whip, Executive Councillor and Leader of the Opposition by turns.^{[citation needed]}

Rise in BJP

BJP suffered badly in 1984 general elections, held after the death of Indira Gandhi. Khurana is credited with reviving the party in India's capital, New Delhi. He worked tirelessly, which earned him the title of 'Dilli Ka Sher' (Lion of Delhi).^[9]

He was the Chief Minister of Delhi from 1993 until he resigned in 1996. The party declined to reinstate him and preferred staying with Sahib Singh Verma.^{[citation needed]}

He along with Kedar Nath Sahani and Vijay Kumar Malhotra kept the party afloat in New Delhi for more than four decades spanning from 1960 to 2000.^{[citation needed]}

The peak of his career saw him serve as the Union Minister of Parliamentary Affairs and Tourism in the Vajpayee government, before resigning in January 1999, owing to a fallout with the senior leadership of the party following a series of attacks on Christians that were blamed on Hindu groups.^[10] He also served as the governor of Rajasthan from 14 January 2004 to 28 October 2004, when he resigned to return to politics in Delhi after about half a dozen MLAs from Delhi went up to him in Jaipur Raj Bhawan requesting that he return to active politics.^{[citation needed]}

On 20 August 2005, Khurana was removed from the BJP for indiscipline for publicly criticising BJP president Lal Krishna Advani and expressing inability and discomfort at serving with him. On 12 September 2005, he was taken back to the party and given back his responsibilities after he apologised about his remarks about the party's leadership.^{[citation needed]}

On 19 March 2006, he was again expelled from the primary membership of the BJP for his anti-party statements. Khurana spoke against the party leadership when he announced that he would attend expelled Saffron Party leader Uma Bharti's rally in Delhi.^[11] Khurana left the BJP, accusing it of not helping solve his cause as committed to giving weight to his mission of developing Delhi.^{[citation needed]}
