Taiwan’s main opposition party fought with ruling party lawmakers to storm the parliament building and occupy the legislative chamber in protest against the nomination of a close aide to the president to a top-level watchdog. Lawmakers from both parties fought outside the building before a group of Kuomintang (KMT) legislators got into parliament’s main chamber, occupying the central podium seeking to prevent a confirmation hearing for former Kaohsiung mayor Chen Chu to head the Control Yuan, an independent government watchdog. Chen is a close aide to President Tsai Ing-wen. KMT lawmakers overturned the stand where Chen was due to speak, unveiling banners reading “no to cronyism, withdraw the nomination”. “We cannot accept this and are resolutely opposed to it,” KMT chairman Johnny Chiang told supporters outside parliament. It is the second time legislators have fought in the past three weeks. Last month fights erupted inside the chamber after lawmakers from the ruling Democratic Progressive Party (DPP) broke through barricades erected by the main opposition Kuomintang (KMT) who had occupied it to protest against government “tyranny”. Chen posted a picture on her Facebook page of herself inside parliament reading papers, saying she was preparing for the hearing. “I hope all parties can get back to official business. We will discuss matters in a democratic parliament and discuss them rationally,” she wrote. The DPP has a large parliamentary majority, and has been angered by the targeting of Chen, who was jailed in 1980 for helping lead pro-democracy demonstrations against the then-KMT government when Taiwan was a dictatorship. The KMT was trounced in January’s parliamentary and presidential elections, having failed to shake off accusations they were too pro-Beijing. The KMT-led Republic of China government fled to Taiwan in 1949 after losing the civil war to the Communist Party.
