2026 年 4 月，台灣政壇爆發一場高度戲劇化的內鬥風波，主角為 李貞秀 與 黃國昌。兩人關係全面破裂，甚至公開隔空對罵，導火線正是李貞秀遭開除黨籍後的強烈反擊。

整起事件的核心爭議，首先集中在所謂的「金錢補償」問題。黃國昌方面指控，李貞秀在辭去立委職務的協商過程中，曾提出需獲得特定金額補償才願意退位，認為這種行為涉及利益交換，嚴重損害政黨形象。然而，李貞秀則強烈否認，反批這是「一派胡言」，並反指是黨中央主動提及補償方案，甚至質疑整件事是精心設計的「設局逼宮」，強調自己不曾也不會接受任何金錢。

除了金錢爭議外，李貞秀更進一步拋出敏感爆料。她聲稱自己在就任立委之前，曾依照黃國昌的指示前往中國辦理放棄國籍，但事後卻遭對方態度丕變、甚至震怒，使她懷疑背後可能存在不為人知的政治盤算。這項說法進一步讓雙方衝突升級，也引發外界高度關注。

在公開發言上，李貞秀的攻擊同樣毫不留情。她直指黃國昌為「偽君子」，批評其政治風格極端，甚至預言其未來無法在新北市長選舉中勝出，並指控其正在將所屬政黨帶往錯誤方向。言詞之激烈，在近年政壇中相當罕見。

另一方面，民眾黨方面則迅速做出處分。2026 年 4 月 13 日，中評會正式決議開除李貞秀黨籍，並列出多項理由，包括指控她以辭職作為籌碼進行對價交易、在媒體與直播中發表未經證實的指控言論（例如涉及 高虹安 與 柯文哲 的金錢爭議）、以及長期違反黨紀、問政表現偏離路線等。隨著黨籍遭開除，她也同步喪失不分區立委資格。

事件的後續影響持續擴大。首先在制度面上，立委席次將出現遞補，預計由學者 許忠信 接替進入立法院。其次在法律層面，台北地檢署已針對李貞秀是否涉及隱匿國籍、詐領薪資等問題展開調查，可能涉及偽造文書、詐欺甚至貪污等刑責，後續發展仍具高度不確定性。

更深層的影響則體現在政治版圖上。此次風波不僅讓支持者之間出現分裂，也使民眾黨內部矛盾全面浮上檯面。在 2026 年底選舉逼近之際，這場內鬥無疑對整體形象與選情構成壓力，未來是否會進一步影響選民支持度，仍有待觀察。

In April 2026, Taiwan’s political scene was shaken by a dramatic internal conflict involving Li Zhenxiu and Huang Kuo-chang. The two figures completely fell out and began publicly trading accusations, following Li Zhenxiu’s expulsion from her party.

At the center of the dispute is a controversy over alleged “financial compensation.” Huang Kuo-chang accused Li of demanding a specific monetary payout during negotiations over her resignation as a legislator, claiming that such behavior amounted to a quid pro quo and seriously damaged the party’s integrity. Li strongly denied the allegation, calling it “completely fabricated,” and countered that it was actually the party leadership that brought up compensation. She further suggested that the entire situation was a deliberate setup designed to force her out, insisting she never intended to accept any money.

The conflict escalated further when Li made additional explosive claims. She alleged that, prior to taking office, she had followed Huang’s instructions to travel to China to handle renunciation of nationality procedures. According to her, Huang later reacted angrily for unclear reasons, leading her to suspect there may have been hidden political motives behind the situation.

Li’s public criticism of Huang was unusually harsh. She openly labeled him a “hypocrite,” criticized his political style as extreme, and even predicted that he would fail in a future bid for mayor of New Taipei City. She also accused him of steering the party toward a dangerous and radical path.

On the other side, the party moved quickly to take disciplinary action. On April 13, 2026, the Taiwan People’s Party formally expelled Li Zhenxiu, citing several reasons. These included allegations that she attempted to use her resignation as leverage for financial gain, made unverified accusations in public (including claims involving Kao Hung-an and Ko Wen-je), and repeatedly violated party discipline. As a result, she also lost her at-large legislator seat.

The aftermath of the incident continues to unfold. Institutionally, her legislative seat is expected to be filled by the next eligible candidate, likely scholar Hsu Chung-hsin. Legally, prosecutors in Taipei have launched investigations into allegations that Li may have concealed nationality status and improperly received legislative salary, potentially involving charges such as document fraud, fraud, and corruption.

More broadly, the incident has exposed internal divisions within the party and caused splits among its supporters. With key elections approaching at the end of 2026, this political infighting could have significant consequences for the party’s public image and electoral prospects.
