Abid Sher Ali, the PML-N candidate for NA-108 Faisalabad, entered a women's polling station in his constituency and argued with a polling agent over discrepancies in the voter lists.
The process was halted for 20 minutes due to the argument.
He said that the reason for the argument is that the lists outside and the ones with the polling officers are different. These discrepancies are causing problems, he said.
A candidate is allowed to enter both male and female polling stations in their constituency, according to analyst Adnan Adil.
