A fourth MLA from the AIADMK’s rebel camp on Tuesday tendered his resignation from the Tamil Nadu Assembly, bringing down the strength of the opposition party in the 234-member House to 43 from 47.

Ambasamudram MLA Esakki Subaya met Speaker JCD Prabhakar and submitted his resignation letter, shortly after AIADMK chief Edappadi K Palaniswami (EPS)-led faction called on the latter with a plea to not to accept the resignation of its three legislators who had stepped down on May 25.
