Bilawal became eligible to contest polls when he turned 25 last month.
Bilawal's father and PPP chief, former President Asif Ali Zardari, yesterday addressed a public rally in Naudero, located close to Larkana, as part of Eid celebrations.
The highlight of the rally was Bilawal mixing freely with people.
Zardari also presided over a meeting of senior PPP leaders yesterday.
