民進黨的前桃園縣長鄭文燦疑似捲入貪汙疑雲，近期以1200萬交保，引發政壇一片譁然。在野黨抨擊，背後疑似是總統賴清德掃除未來的競爭對手。這讓人聯想到過去國民黨也曾發生過的嚴重內鬥事件，當時馬英九舉發同黨的立法院長王金平關說並要求其下台，這便是台灣政壇史上著名的馬王政爭。

2013年，台灣政壇爆發一件震動全國的政治事件，即所謂的「王金平關說案」。當時的立法院長王金平被指控涉嫌利用其職權進行司法關說，干預司法案件。這一事件涉及的核心人物包括立法院長王金平、法務部長曾勇夫和高檢署檢察長陳守煌。

事情始於2013年，特偵組（特別偵查組）針對國民黨立委柯建銘涉嫌在2010年涉及的一宗關說案進行調查。在調查過程中，特偵組通過監聽發現，王金平、曾勇夫和陳守煌涉嫌利用其職權進行關說，干預司法程序。

2013年9月6日，時任總統兼國民黨主席的馬英九召開記者會，公開指控王金平利用其職權進行司法關說，並表達對此行為的強烈譴責。馬英九表示，這一行為損害司法獨立，違背法治精神，要求王金平為此負責並下台。

而王金平在事件曝光後返回台灣，公開否認所有指控，表示自己沒有從事關說行為，並強調自己一直尊重司法獨立。他的支持者也表示，這是一場政治鬥爭，馬英九是在利用此事打擊王金平，清除黨內異己。

在馬英九的強烈要求下，國民黨於2013年9月11日決定撤銷王金平的黨籍。這一決定意味著王金平將失去立法院長的職位，因為根據台灣的法律，立法院長必須是立法委員，而不分區立委的身份又必須有政黨背景。王金平對此不滿決定提起訴訟，要求法院撤銷國民黨的決定。最終，台北地方法院裁定國民黨撤銷黨籍的決定無效，王金平得以保留立法院長的職位。

馬英九揭發王金平的主要原因可以歸納為以下幾點：

首先，王金平的行為違反司法獨立的原則，影響法治的公正性。他希望通過揭發此事，維護司法體系的獨立性和公正性。其次，國民黨內部的派系鬥爭也是一個不可忽視的因素。馬英九與王金平分屬不同的黨內派系，兩人在政策和權力分配上存在分歧。揭發王金平，對馬英九來說也是清除異己、鞏固自己黨內領導地位的手段。最後，馬英九希望藉此樹立自己在反貪腐和維護司法正義方面的形象，向社會展示他對政治道德的堅持和對貪腐行為的零容忍態度。

「王金平關說案」對台灣政壇產生深遠的影響。這一事件不僅引發國民黨內部的分裂，也使得國民黨在後來的選舉中失去大量支持者，影響其在台灣政治舞台上的地位。此外，這一事件也讓社會大眾對台灣政治圈的權力鬥爭和司法獨立問題有更深的認識和反思。

當時的政治評論家表示兩人的衝突在於與大陸簽訂服貿協議的認知，馬英九長期對於當時國民黨擁有多數席次的立法院，卻無法推動想要的法案感到不滿。而後來爆發的太陽花運動，王金平採取相當被動的方式處理，不願強制驅離被學生霸佔的立法院，造成整個國家議事的癱瘓，這些都是造成馬英九決定親自與王金平對抗的導火線。而國民黨本土派的支持者表示，馬英九在王金平2013年9月6日早上遠赴馬來西亞參加女兒婚禮的時候發動突襲，要求王金平自動請辭院長的行為相當不厚道。王金平當時回國後，在機場馬上發表演說，周圍全部都是國民黨的立委，表達支持的決心。當時國民黨分裂相當嚴重，也造成民進黨的蔡英文後來輕鬆打敗朱立倫贏得總統大選的主要原因。

Former Taoyuan County Magistrate Zheng Wencan of the Democratic Progressive Party (DPP) has recently been implicated in a corruption scandal and was released on bail of 12 million NTD, sparking an uproar in the political arena. The opposition parties have criticized the situation, suggesting that it might be President Lai Ching-te's way of eliminating future rivals. This brings to mind the serious internal strife that previously occurred within the Kuomintang (KMT), notably when Ma Ying-jeou accused his fellow party member and Legislative Yuan President Wang Jin-pyng of influence peddling and demanded his resignation, an event known as the "Ma-Wang Conflict" in Taiwan's political history.

In 2013, Taiwan's political scene was rocked by a significant scandal known as the "Wang Jin-pyng Influence Peddling Case." At that time, Legislative Yuan President Wang Jin-pyng was accused of using his position to interfere with judicial proceedings. The core figures involved in this scandal included Legislative Yuan President Wang Jin-pyng, Minister of Justice Tseng Yung-fu, and High Prosecutor's Office Chief Prosecutor Chen Shou-huang.

The affair began in 2013 when the Special Investigation Division (SID) investigated KMT legislator Ker Chien-ming for his alleged involvement in an influence peddling case from 2010. During the investigation, the SID discovered through wiretapping that Wang Jin-pyng, Tseng Yung-fu, and Chen Shou-huang were allegedly using their positions to influence judicial processes.

On September 6, 2013, Ma Ying-jeou, who was the President and KMT Chairman at the time, held a press conference to publicly accuse Wang Jin-pyng of using his position for judicial influence peddling, expressing strong condemnation for such actions. Ma Ying-jeou stated that this behavior undermined judicial independence and violated the principles of the rule of law, demanding that Wang Jin-pyng take responsibility and step down.

Upon returning to Taiwan after the accusations, Wang Jin-pyng publicly denied all charges, asserting that he had not engaged in any influence peddling and emphasizing his consistent respect for judicial independence. Wang's supporters claimed that this was a political maneuver by Ma Ying-jeou to eliminate Wang Jin-pyng and remove internal dissent within the party.

Following Ma Ying-jeou's insistence, the KMT decided on September 11, 2013, to revoke Wang Jin-pyng's party membership. This decision meant that Wang would lose his position as Legislative Yuan President since, under Taiwanese law, the Legislative Yuan President must be a legislator, and an at-large legislator's status requires party affiliation. Wang Jin-pyng, dissatisfied with this decision, filed a lawsuit to have the court overturn the KMT's decision. Ultimately, the Taipei District Court ruled that the KMT's decision to revoke his party membership was invalid, allowing Wang Jin-pyng to retain his position as Legislative Yuan President.

The main reasons behind Ma Ying-jeou's decision to expose Wang Jin-pyng can be summarized as follows:

Firstly, Wang Jin-pyng's actions were seen as violating the principle of judicial independence and affecting the fairness of the rule of law. Ma Ying-jeou aimed to uphold the independence and integrity of the judicial system by exposing this issue.

Secondly, internal factional strife within the KMT was also a significant factor. Ma Ying-jeou and Wang Jin-pyng belonged to different factions within the party, and there were differences in policies and power distribution between them. By exposing Wang Jin-pyng, Ma sought to eliminate internal opposition and consolidate his leadership within the party.

Lastly, Ma Ying-jeou hoped to establish his image in the fight against corruption and the maintenance of judicial justice, demonstrating to society his commitment to political ethics and zero tolerance for corrupt behavior.

The "Wang Jin-pyng Influence Peddling Case" had far-reaching impacts on Taiwan's political landscape. This incident not only caused a split within the KMT but also led to a significant loss of support for the party in subsequent elections, affecting its standing on Taiwan's political stage. Additionally, the case prompted the public to gain a deeper understanding and reflection on power struggles and judicial independence within Taiwanese politics.

Political commentators at the time suggested that the conflict stemmed from differing views on the Cross-Strait Service Trade Agreement with China. Ma Ying-jeou had long been frustrated by the Legislative Yuan, dominated by the KMT, failing to pass desired legislation. The subsequent Sunflower Movement, during which Wang Jin-pyng took a passive approach and refused to forcefully evict the student protesters occupying the Legislative Yuan, paralyzing national proceedings, further exacerbated the conflict between Ma and Wang.

KMT local faction supporters also criticized Ma Ying-jeou for launching his attack while Wang Jin-pyng was attending his daughter's wedding in Malaysia on September 6, 2013, deeming it highly unethical. Upon Wang's return to Taiwan, he delivered a speech at the airport, surrounded by KMT legislators showing their support. The severe internal division within the KMT contributed to Tsai Ing-wen of the DPP easily defeating Eric Chu in the subsequent presidential election.
