Jakarta – The Independent Election Monitoring Committee (KIPP) has filed a report against two political parties, the Nasdem Party and the Gerindra Party, with the Election Supervisory Committee (Bawaslu) for allegedly violating campaign regulations.

The reports, filed on Tuesday, accused the parties of staging an outdoor campaign, an activity permitted to only be carried out between March 16 and April 5.

"The Bawaslu has to study the case and forward it to the General Elections Commission [KPU]," KIPP deputy secretary-general Girindra Sandino said at the Bawaslu headquarters in Central Jakarta.

He said that Nasdem was guilty of gathering supporters in an outdoor venue, Gelora Bung Karno stadium in Senayan, Jakarta, on Sunday.

Gerindra deputy secretary-general and legislative candidate Aryo Djojohadikusumo was also accused of violating campaign regulations for gathering more than 20,000 people for an event on Sunday.

Both Nasdem and Aryo are also suspected of involving children in the events. "We submitted photos of children participating [in those events]. We also submitted proof of vote-buying," Girindra said.

Nasdem secretary-general Rio Patrice Capella denied the accusations, arguing that the gathering had taken place indoors. He also said that only party members attended the rally.

"We have also discussed the matter with the Bawaslu. After we got a recommendation from the Bawaslu, we decided to proceed with the event," Rio said. Aryo did not return a phone call from The Jakarta Post.
