The Pakistan Muslim League (Nawaz) (Urdu: پاکستان مسلم لیگ (ن), abbr. PML(N) or PML-N) is a centre-right, conservative liberal political party in Pakistan. It is currently the third-largest party in the Senate. The party was founded in 1993, when a number of prominent conservative politicians in the country joined hands after the dissolution of Islamic Democratic Alliance, under the leadership of former Prime Minister Nawaz Sharif. The party's platform is generally conservative, which involves supporting free markets, deregulation, lower taxes and private ownership. Although the party historically supported social conservatism, in recent years, the party's political ideology and platform has become more liberal on social and cultural issues; however, members have been accused of using Islamist populist rhetoric. Alongside the Pakistan Tehreek-e-Insaf (PTI) and Pakistan People's Party (PPP), it is one of the three major political parties of the country.
