Historically, despite the tremendous influence exerted by Islam on public life, religious parties and organisations have historically failed to do well at the ballot box, receiving an average of only 6% of votes cast in elections since the 1980s. Focusing on the case of the Tehreek-i-Labbaik Pakistan (TLP), a new Barelvi political party and social movement that has campaigned on the emotive issue of blasphemy since being formed in 2015, this article argues that the clientelistic, patronage-based nature of democratic politics in Punjab, coupled with factionalism and competition within the religious right, continues to play a role in limiting the electoral prospects of religious parties. Nonetheless, as was seen in the General Elections of 2018 in which the TLP outperformed expectations, there are particular circumstances in which the religious parties are able to make electoral breakthroughs. While the TLP was able to make effective use of populist rhetoric to garner some genuine support for itself, this article argues that the organisations sustained campaign of protests over the issue of blasphemy fed into broader efforts by the military establishment and opposition political parties to destabilise and weaken the government of the PML-N prior to the 2018 elections.
