K Annamalai, the chief of BJP's Tamil Nadu unit, today asked party workers to strengthen its hold in the state to take on the ruling DMK after losing AIADMK, an important ally, from the National Democratic Alliance (NDA), sources said. The Tamil Nadu BJP chief urged his party's district Presidents and state office bearers to work very hard to expand BJP's negligible presence in the state and to capitalise on what he calls the Modi government's performance, sources said. After losing its ally, the AIADMK, ahead of the 2024 Lok Sabha polls, the BJP has no strong political party on its side yet in Tamil Nadu.
