Pakistan Muslim League-Nawaz (PML-N) leader Chaudhry Nawaz and Pakistan Tehreek-e-Insaf (PTI)-backed Sunni Ittehad council candidate Chaudhry Moonis Elahi are competing in the by-polls from PP-158.

Chaudhry Moonis Elahi is the son of the former chief minister of Punjab, Chaudhry Pervaiz Elahi.

Earlier in March, an appellate tribunal of the Lahore High Court (LHC) allowed Moonis Elahi to contest by-polls.
