A heated argument broke out between former Prime Minister Ranil Wickremesinghe and SJB MP Suresh Vadiwel in Parliament earlier today.

"Ask this mad man to sit down," Wickrenesinghe asked Speaker Mainda Yapa Abeywardena as Vadiwel kept interrupting the former Prime Minister's speech.

The argument took place over a trade union previously affiliated with the UNP. A court case is currently underway over the "ownership" of the trade union.
