Jakarta – The House of Representatives' two smallest parties – the Great Indonesia Movement Party (Gerindra) and the People's Conscience Party (Hanura) – have pledged to keep the government in check.

"Our party will be critical, but also constructive. Despite the fact that we are a small bloc, it is not a problem, because that is not the substantive issue of a democracy," Hanura secretary-general Yus Usman told The Jakarta Post in Jakarta on Thursday.

Yus said that his party planned to monitor the government to ensure its agenda was conducted properly.

"President Susilo Bambang Yudhoyono said many times during his campaign that he would continue the fight against corruption. We want to make sure that such a promise will be fulfilled," he said.

Separately, Gerindra secretary-general Ahmad Muzani said that his party had yet to determine its final political stance, however, he said the party would not have any problems if it chose to play the opposition role. "The decision will be made by our chief patron, Prabowo Subianto," he said.

Like Yus, Ahmad also said that his party would ensure that Yudhoyono would live up to his promises. Gerindra and Hanura occupy only 43 out of 560 seats at the House of Representatives.
