Opponents of the Taiwanese president plan to march in strongholds of the ruling party Opponents of Taiwanese President Chen Shui-bian are planning to take their protests to several cities across the island, starting on Friday in the southern city of Kaohsiung, the traditional stronghold of the ruling Democratic Progressive Party. The new round of 'besiege the city' protests comes after more than 380,000 red-clad anti-Chen protesters formed a 5.5km circle around the Presidential Office on Friday night. 'On September 29, we will stage a 'besiege the city' march in Kaohsiung to show the strength of the people against Ah Bian,' said Jerry Fan Ke-chin, activity spokesman for the 'Million Voices Against Corruption' campaign, referring to Mr Chen's nickname. Mr Chen, who won the presidency in 2000 and again in 2004 by wafer-thin margins, has come under pressure to step down since May over a string of scandals implicating him and his family. He was questioned over alleged embezzlement of NT$36 million (HK$8.5 million) in state funds, while his wife is being investigated for alleged influence peddling and their son-in-law has been indicted on suspicion of insider trading and taking bribes. Mr Fan said to facilitate the march, campaign organisers would first form a regional office in the southern port city tomorrow. He said there was a need to promote the campaign in the south of the island because this was where Mr Chen enjoyed most support. Mr Fan said organisers might hold other 'besiege the city' marches in Taoyuan in northern Taiwan, Taichung in central Taiwan, Tainan in the south and Hualien in the east to extend the pressure on Mr Chen. But for the time being, no detailed plans had been made, he added. Shih Ming-teh, the former chairman of the DPP who started the anti-Chen campaign last month, will lead protesters to continue their sit-in outside Taipei Train Station, where they would remain until Wednesday, Mr Fan said. The following day Mr Shih will lead protesters back to the boulevard outside the Presidential Office for another sit-in. On Friday, campaign organisers hope one million motorists will take part in a 'besiege the island' circuit. Mr Shih, a former ally of Mr Chen, started the sit-ins in front of the Presidential Office on September 9, but the activity was interrupted after the pro-Chen camp got police approval to stage a series of activities in support of Mr Chen from yesterday until Wednesday. This tactic forced Mr Shih to change the protest venue to the train station on Friday and to stage the symbolic 'besiege the city' march, which was billed as Taiwan's largest single gathering ever staged by people out of their own will. Most large-scale protests in the past were mobilised by political parties or interest groups. At the conclusion of the march, a visibly moved Mr Shih knelt down at the train station protest venue to thank God for the success of the march and to praise the Taiwanese for their strength and determination to stamp out corruption. Taiwan's opposition parties and Beijing are hoping that the DPP will be unseated in presidential elections in 2008. Mr Chen is not eligible to run again. The mainland has largely kept silent about the protests for fear that any comments could be used by Mr Chen to prop up his position.
