Taipei mayor Wayne Chiang Wan-an has emerged as a prominent political figure following a large opposition protest over a recent food safety scandal involving contaminated soybean salad oil. Organisers estimated that more than 200,000 people participated in the demonstration on Saturday outside the office of Taiwanese leader William Lai Chiang-te, marking the largest opposition rally since Lai took office two years ago.
The protest centred on public outrage over the government’s handling of the scandal, which involved soybean oil found to contain elevated levels of a carcinogenic substance. Demonstrators called for an apology from Lai and demanded the resignation of Premier Cho Jung-tai, accusing the administration of prioritising business interests over public health and moving too quickly to return the tainted products to supermarket shelves without adequate explanation or safeguards.
Chiang, representing the island’s main opposition party, the Kuomintang (KMT), criticised the government’s response and urged Lai to address the public’s concerns. He also indicated openness to a no-confidence vote against Cho if the opposition parties could reach an agreement.
Government officials expressed respect for the right to protest but rejected opposition claims that widespread dissatisfaction was driving the rally. The Democratic Progressive Party (DPP), now in power, labelled the event as politically motivated, with legislator Chen Pei-yu describing it as a “political farce” and spokesperson Lin Chuin calling it “a fake protest but a real political mobilisation.” They accused Chiang and other KMT figures of exploiting the crisis to advance their political agendas instead of focusing on improving food safety.
Political analysts noted that the large turnout and Chiang’s vocal role have revitalised the KMT ahead of local elections scheduled for November and could influence the contest to select the party’s candidate for the 2028 leadership election. Chang Yuan-hsiang, a political science professor at Soochow University, observed that the protest demonstrated food safety’s potential to mobilise the public beyond traditional party loyalties, while also cautioning that maintaining this momentum will depend on whether the issue remains salient to voters.
Commentator Shen Cheng-nan described the rally as a pivotal moment for Chiang, establishing him as a key consensus leader within the KMT-led opposition camp. Media reports highlighted Chiang’s rising stature when he received prolonged applause upon addressing the crowd at the event.
A recent poll by the Taiwan Inspiration Association showed Chiang leading potential KMT presidential hopefuls with 30 percent support, ahead of Taichung mayor Lu Show-yen at 22.7 percent and legislator speaker Han Kuo-yu at 19 percent. Chiang also held the highest favourability rating among leading politicians at 48.6 percent, surpassing Lai’s 44.9 percent and Lu’s 40.8 percent.
The protest and ensuing political developments suggest the food safety scandal has become a focal point in Taiwan’s evolving political landscape, with opposition figures leveraging public discontent as elections approach. However, analysts caution that the issue’s electoral significance may diminish if other concerns take precedence before November’s vote.
