Nabil Gabol entered politics at the age of 24 as a member of the
Pakistan Peoples Party (PPP). He was re-elected to the Provincial Assembly of Sindh as a candidate of PPP from Constituency PS-88 (Karachi South-IV) in the
1993 Pakistani general election. He received 21,587 votes and defeated Muhammad Aslam, a candidate of
Haq Parast Group (HPG). He ran for the seat of the Provincial Assembly of Sindh as a candidate of PPP from Constituency PS-88 (Karachi South-IV) in the
1997 Pakistani general election but was unsuccessful. He received 11,968 votes and lost the seat to Liaquat Ali Qureshi, a candidate of HPG.
2008 election He was re-elected to the National Assembly as a candidate of PPP from Constituency NA-248 (Karachi-X) in the
2008 Pakistani general election. He received 84,217 votes and defeated
Abdul Shakoor Shad. In November 2008, he was inducted into the federal cabinet of prime minister
Yousaf Raza Gillani and was appointed as
Minister of State for Ports and Shipping. As minister of state, he inaugurated the
Gwadar Port in December 2008. He was included in the special team of the PPP to resolve the
political crisis in Balochistan in March 2009. He met with the political and tribal leaders of Balochistan to solve the problems of the Baloch people. However, as of 2015, despite the court's orders, the government had not recalled Nadir, who was serving as the officer in charge of the
machine readable passport section at the Consulate General. He served as Minister of State for Ports and Shipping until February 2011. He resigned from the post saying that he had failed to address the problems of voters in his constituency during his tenure. Political analysts say that the resignation stemmed rather from an internal PPP tug-of-war between Gabol and
Asif Ali Zardari.
2013 election After he was marginalized by the PPP leadership, he announced his decision to quit the PPP in 2013 and he joined, along with his colleagues, the
Muttahida Qaumi Movement (MQM). He said that PPP was no longer the party of
Benazir Bhutto and therefore he left it. His decision to join the MQM, a
Muhajir nationalist party traditionally opposed to the PPP, caused a stir in the politics of Sindh, especially Karachi and Lyari as Gabol comes from a political family long associated with the PPP. Journalist Yousuf Masti Khan said that the decision was driven by power politics due to different political party gangs (including MQM's
Nadeem Commando and PPP's
People's Aman Committee) ruling Lyari and with weakened prospects of the PPP in the upcoming elections. During a 2015 interview on
Geo News, he alleged electoral rigging in his constituency, NA-246 (Karachi-VIII), from which he emerged victorious in the 2013 general elections. He recounted visiting polling stations on election day and observing minimal voter turnout. He claimed to have been informed that his victory was assured and that voters were not required. Furthermore, he expressed surprise upon discovering that he had received 140,000 votes despite the reported low voter turnout. In 2015, MQM demanded Gabol's resignation from the National Assembly seat. Following which, he quit MQM and relinquished his National Assembly seat. In 2016, Gabol declared his support for
Imran Khan and announced joining the protest organized by
Pakistan Tehreek-e-Insaf (PTI). Afterward, he announced his intention to organize a public gathering to determine whether he should rejoin PPP or join the PTI. In February 2017, he re-joined PPP along with his son Nadir. Opinions among residents of Lyari regarding Gabol's return to the PPP were divided, with some considering him irrelevant to Lyari's politics and holding him accountable for the presence of gangs in the area. PPP politicians in
District South also expressed discontent, stating that the PPP leadership had not consulted them before readmitting Gabol into the party and emphasized his notoriety in Lyari. Additionally, there were rumors suggesting that Gabol was considering joining either the PTI or the
Pakistan Muslim League-N (PML-N). However, a faction within the PTI Sindh opposed his inclusion in the party, leading to his decision to rejoin the PPP.
2024 election He was re-elected to the National Assembly in the
2024 Pakistani general election as a candidate of the PPP from constituency
NA-239 Karachi South-I. He received 40,077 votes, defeating PTI-backed independent candidate Mohammad Yasir Baloch, who received 37,234 votes. Baloch alleged election irregularities and contested Gabol's victory. However, the
Election Commission of Pakistan (ECP) dismissed the petition and instructed Baloch to contest the constituency results in an election tribunal. ==Lyari unrest==
