Former Punjab chief minister Chaudhry Parvez Elahi was locking horns against Pakistan Muslim League-Quaid (PML-Q) candidate and nephew Musa Elahi from PP-32 Gujrat.
According to details, the seat fell vacant after Chaudhry Salik Hussain retained his National Assembly seat.
Last month, the PTI stalwart decided and announced to contest the by-polls.
The family members met Parvez Elahi in jail and signed the nomination papers for the by-election.
In an informal conversation with journalists at the FIA court, Elahi said: “Ban on meetings in Adiala Jail is unconstitutional. They cheated the people by putting PTI's mandate. The people are already crushed, their self-esteem is being further undermined,” former chief minister of Punjab and former speaker of the Punjab Assembly said.
“Form-45 will become a trap for these fake rulers,” Parvez Elahi claimed.
