Jakarta. The main political party backing presidential candidate pair Prabowo Subianto and Sandiaga Uno said on Thursday that it plans to reject the official results of the 2019 presidential and legislative elections.

Anggawira, deputy secretary general of the opposition Great Indonesia Movement Party (Gerindra), told Suara Pembaruan that Prabowo, as party chairman, said as much.

The Prabowo-Sandiaga camp has stated on various occasions over the past month that it would not accept the result of the presidential election, which the General Elections Commission (KPU) is scheduled to announce on May 22.

Indonesia held its first simultaneous presidential and legislative elections on April 17.

"It will be odd if we only reject one [the result of the presidential election], but accept the other [the result of the legislative election], while they were held simultaneously. So Gerindra will reject both," Anggawira said.

This course of action would leave the party without representation in the national legislature. However, Anggawira said the party chooses to continue its fight outside the House of Representatives to further its aspirations.

"This is the risk of struggle. We must be consistent. However, we haven't received any further directives from Mr. Prabowo," added Anggawira, who was elected as a lawmaker in last month's elections.

"We are still waiting for a final decision on what Mr. Prabowo said before [on Tuesday] … but if we reject the result of the presidential election, we must also refuse to accept the result of the legislative election," he reiterated.

Anggawira declined to comment on the stance of the other political parties in the Prabowo-Sandiaga camp.

Only two candidate pairs, Prabowo and Sandiaga, and incumbent Joko "Jokowi" Widodo and his running mate Ma'ruf Amin, competed in last month's presidential election.

Quick-count results released by several reputable pollsters on election day showed between 54 percent and 56 percent of the vote in favor to Jokowi-Ma'ruf.

As of Thursday evening, with 85.4 percent of the ballots already counted by the KPU, Jokowi-Ma'ruf had secured 56.06 percent of the vote and Prabowo-Sandiaga 43.94 percent.

Prabowo rejected the KPU's official tabulation on Tuesday, describing it as "fraudulent."

The pair's national campaign team previously said it would only refuse to accept the result of the presidential election.

Prabowo and Sandiaga were supported by Gerindra, the National Mandate Party (PAN), Berkarya Party, Prosperous Justice Party (PKS) and the Democratic Party.
