The tension between Health Minister Chua Jui Meng and DAP chairperson Lim Kit Siang over the dengue epidemic reached a feverish height today with the latter challenging the minister to a "tell all and clear all session".

"If Chua is not prepared to accept my challenge, I am prepared to go to Parliament early next week to give a full briefing to the members about Chua's irresponsible mishandling of the dengue epidemic," said Lim when contacted.
