The bypoll for the Erode East assembly seat in Tamil Nadu has turned into a high stakes battle for both the ruling DMK and the opposition AIADMK. The DMK sees this as a referendum on Chief Minister M K Stalin's 19-month-long government and a prelude to the 2024 Lok Sabha polls. NDTV's Sam Daniel spoke to veteran leader EVKS Elangovan, the Congress candidate as part of the DMK alliance, whose son's death necessitated the bypoll.
