The gesture by Municipal Administration and Water Supply Minister K P Munusamy counselling his party colleague was greeted by mild thumping of desks by the DMK members.
It all started when AIADMK member K Kuppan representing Thiruvottiyur alleged that Karunanidhi had "given away" Katchatheevu islet -- a bone of contention between Indian and Sri Lankan fishermen -- to Sri Lanka
While Kuppan tried to continue with his allegation, Munusamy rose from his seat and requested the Speaker not to allow his party MLA to make allegations during the Question Hour, saying it has not been the Assembly's tradition to make allegations during the Question Hour.
DMK members had walked out of the House on several occasions and even been evicted during the current session when they staged noisy protests against critical remarks targeting Karunanidhi or the party.
