<h3>Overview</h3> <p>The <span class="key-term" data-definition="All India Anna Dravida Munnetra Kazhagam – a major regional party in Tamil Nadu, often in opposition at the state level (GS2: Polity)">AIADMK</span> is on the brink of a split after a second consecutive defeat in the 2026 Assembly election. All <strong>47 MLAs</strong> of the party are divided over the leadership of General Secretary <strong>Edappadi K. Palaniswami</strong>, who until recently served as Leader of Opposition. Two rival groups have lodged written claims with the <span class="key-term" data-definition="Pro-tem Speaker – a temporary presiding officer appointed to oversee the first meeting of a newly elected legislative assembly (GS2: Polity)">Pro-tem Speaker</span> <strong>M.V. Karuppiah</strong>. </p> <h3>Key Developments</h3> <ul> <li>Both factions submitted separate letters to the speaker on Monday, seeking recognition as the legitimate legislature party.</li> <li>The dissident bloc, led by former ministers <strong>C.

The faction also plans to invoke paragraph <strong>2(1)(b) of the 1985 <span class="key-term" data-definition="Anti-defection law – legislation that curbs floor‑crossing by disqualifying members who defy the party whip, thereby ensuring party discipline (GS2: Polity)">anti‑defection law</span></strong> to disqualify any rebel MLA who votes against the government.</p> <p>If the Shanmugam‑Velumani faction merges with the TVK, it would need the support of at least <strong>32 legislators</strong> (the majority of the AIADMK’s 47 seats). A recent parallel is the merger of seven AAP MPs in the Rajya Sabha with the BJP, approved by the Vice‑President and Rajya Sabha Chairman <strong>C.P.

The outcome will determine whether the AIADMK remains a unified opposition or fragments further, influencing the stability of the TVK government and the upcoming trust vote. Continued political churn in Tamil Nadu is expected until a clear leadership emerges.</p>
