Jan 26, Colombo: Sri Lanka's main opposition United National Party (UNP) has imposed a ban on its members from organizing any self-promoting activities.

Party Leader Ranil Wickremasinghe has directed that all public representatives and electoral organizers should halt all non-political activities.

The party leader has issued that directive under the power vested on him by the party constitution and has called on party members to participate in programs that fall under the political plan of the UNP.

UNP General Secretary Tissa Attanayake has said that party members would therefore be unable to participate in any social welfare activity that is not approved by the party.
