General elections were held in Pakistan on 25 July 2018 to elect the members of the 15th National Assembly and the four Provincial Assemblies. The three major parties were Pakistan Tehreek-e-Insaf (PTI), led by Imran Khan, the Pakistan Muslim League, led by Shehbaz Sharif, and the Pakistan People's Party, led by Bilawal Bhutto. The PTI won the most seats in the National Assembly but fell short of a majority; the party subsequently formed a coalition government with several smaller parties. At the provincial level, the PTI remained the largest party in Khyber Pakhtunkhwa (KP); the Pakistan Peoples Party (PPP) retained its dominance in Sindh; and the newly formed Balochistan Awami Party (BAP) emerged as the largest party in Balochistan. In Punjab, the result was a hung parliament, with the Pakistan Muslim League (N) winning the most seats. However, after several independent MPAs joined the PTI, the latter became the largest party and was able to form a government.

The Pakistan Tehreek-e-Insaf is a political party in Pakistan established in 1996 by Pakistani cricketer and politician Imran Khan, who served as the country's prime minister from 2018 to 2022. The PTI ranks among the three major Pakistani political parties alongside the Pakistan Muslim League–Nawaz (PML–N) and the Pakistan People's Party (PPP), and it is the largest party in terms of representation in the National Assembly of Pakistan since the 2018 general election. With over 10 million members in Pakistan and abroad, it claims to be the country's largest political party by primary membership, as well as one of the largest political parties in the world.
