The Minister made these comments following a observation tour at Magampura Port in Hambantota.
Those who identify themselves as the joint opposition have created a major issue in this country, he said.
Just as a country should have discipline, a party too should be disciplined, the minister said, adding that justice and goodness will not prevail where there is no discipline.
Ranatunga further stated that he requests the President to immediately safeguard party discipline if he loves the party.
