Malang, East Java – Prosperous Justice Party (PKS) chairman Luthfi Hasan Ishaaq has said recent problems that have hit his party were contrived by other parties as a test.

"Given the PKS' age [13 this year], which is that of reaching puberty, it's not surprising that many have come to tease us," he said in a East Java regional meeting on Friday as quoted by kompas.com.

The party's reputation has been rocked by a spate of scandals in the past month. The latest embarrassment saw PKS lawmaker Arifinto photographed by a journalist watching porn on his tablet computer during a House of Representatives plenary meeting. Previously, PKS founder Yusuf Supendi published claims that PKS politicians were not reputable.

"PKS is simply the target of teasing by other parties. We have to be patient." He said Arifinto's case had been set up by another party.

Media Indonesia photojournalist M. Irfan, who took the photos of Arifinto watching porn, said that when he had taken the pictures – about 60 in total – he had not known who Arifinto was.
