Rival political camps yesterday mobilised about 200,000 supporters to take to the streets in Taipei in the so-called 'Super Sunday' rallies, six days ahead of legislative polls. Areas surrounding the Presidential Office were packed with supporters of the pro-independence Taiwan Solidarity Union (TSU), who chanted slogans on national identity. Calling for the island's official name, the Republic of China, to be changed to Taiwan, they marched from the Chiang Kai-shek Memorial Hall to the boulevard in front of the Presidential Office. In the wake of the TSU rally, President Chen Shui-bian said that within two years he would re- place the words China, Republic of China and Taipei in the names of government-run companies and overseas offices with the word Taiwan. Small clashes were reported as TSU supporters passed the headquarters of the opposition Kuomintang, which held a big rally nearby. Authorities sent 1,500 police to head off violence between the rivals. Police were on edge over information that apparently indicated former president Lee Teng-hui, regarded by the TSU as its spiritual leader, would be assassinated. Officers also claimed they had information about assassination plots against KMT chairman Lien Chan. Defying the warnings, Mr Lee told the TSU rally that the party was no longer a vessel of the ruling Democratic Progressive Party, an informal ally of the TSU. '[The TSU] has made big contributions to rectifying the status of Taiwan and its title,' Mr Lee told the crowd, estimated at 100,000 by independent observers. Nearby, Mr Lien attacked the TSU, saying its actions would only bring disaster. He also accused President Chen of the pro-independence DPP of being the source of chaos in Taiwan. 'The ruling camp says it wants to destroy the country, destroy the Republic of China. It wants to change the history of the country. Its so-called ally proposes the establishment of Taiwan [as a] nation,' Mr Lien said in front of about 100,000 supporters. However, what his opponents were really doing, he said, was creating 'cross-strait tensions, treating the other side of the Taiwan Strait as an enemy, and now pushing us to a state of war'. The DPP did not join the TSU in the Taipei march. Instead, it organised four large motorcades to parade in four cities and counties in central Taiwan to solicit voters' support.
