Taiwanese prosecutors have charged the island's vice-president and two other senior officials of corruption and document forgery but spared the ruling party's presidential and vice-presidential candidates. After a closely watched investigation into alleged misuse of funds by five heavyweights of the ruling Democratic Progressive Party, prosecutors yesterday cleared DPP presidential candidate Frank Hsieh Chang-ting and his running mate, Su Tseng-chang, of corruption allegations for lack of evidence. But Vice-President Annette Lu Hsiu-lien, DPP chairman Yu Shyi-kun and National Security Council secretary general Mark Chen Tan-sun were indicted for allegedly using receipts provided by others to make spending claims from the controversial special monthly allowances set aside for them for public use. Prosecutor Chen Yun-nan, the spokesman for the Special Investigation Taskforce, said Lu had allegedly made false claims worth NT$5.63 million (HK$1.33 million) between December 2000 and May 2006 during her time as vice-president. He said Yu had allegedly made false claims worth NT$2.38 million between October 2000 and December 2005 during his time as secretary general of the Presidential Office and premier. Mark Chen allegedly made false claims of NT$368,199 between July 2004 and June 2006 during his terms as foreign minister and presidential secretary general. The prosecutor said the three were indicted because they had allegedly instructed their aides to collect the receipts, unlike the opposition Kuomintang presidential candidate, Ma Ying-jeou, who was found not guilty last month on the grounds that he had not asked anyone to collect receipts for his spending claims. Mr Ma was charged in February with embezzling over NT$11 million in special monthly allowances, funds traditionally treated as private subsidies for government heads until DPP lawmakers accused Mr Ma of stealing government money. Mr Ma was subsequently acquitted. The DPP officials were investigated following a tit-for-tat action by KMT lawmakers. Lu said she had never instructed anyone to collect any receipts for her and had fully co-operated with the prosecutors. 'You prosecutors, will you be able to sleep [without regret] at night?' she asked. Yu, who is visiting Canada, offered to resign in line with a previous promise to step down if indicted. In a statement, he said he was clean and had never embezzled any government funds.
