Taiwanese President Chen Shui-bian will face strong pressure to step down as chairman of his ruling Democratic Progressive Party today after its poor showing in the weekend's polls. Some DPP members say Mr Chen may announce his resignation at the meeting of the party's central committee, where the DPP will review the election results. But even if he does quit, it will only take effect in February during the cabinet reshuffle. Pressure for Mr Chen to shoulder responsibility for the party's poor performance has mounted since the close of Saturday's elections. The DPP only won 89 seats, far short of the 101 it had predicted. It was seeking to secure a majority in the 225-seat legislature with the aid of its informal ally, the Taiwan Solidarity Union, which grabbed just 12 seats. Party stalwarts are upset that at least 13 top DPP legislators, including Shen Fu-hsiung and Tuan Yi-kang, failed to win re-election. They have blamed the poor result on campaign strategies such as vote allocations and pro-independence appeals that scared away neutral voters. 'According to tradition, the party chairman must take responsibility for an election defeat,' said Lee Chun-yi, head of the DPP legislative caucus. He said Mr Chen could act as a co-ordinator or moderator for all political parties after resigning as DPP leader. Meanwhile, TSU chairman Huang Chu-wen yesterday offered to resign to take responsibility for the party's poor showing. But the party decided to let former president Lee Teng-hui, the party's spiritual leader, decide whether to allow Mr Huang his proxy, to resign.
