Opposition DMK on Monday boycotted Chief Minister K Palaniswami's reply in the Tamil Nadu assembly to a debate on grants for departments held by him, protesting the Speaker's refusal to review his order expunging some remarks made by party leader M K Stalin.

Stalin, the Leader of the opposition, made certain remarks during a wordy duel between the arch-rivals ruling AIADMK and DMK over the proposed eight-lane greenfield highway connecting Salem and Chennai.
