"If he is going abroad, he will have to get permission from the Governor (the President's appointee in-charge of the province)," Rambukwella told reporters at the weekly cabinet press briefing.
Wigneswaran's Tamil National Alliance (TNA) leaders last month travelled to New Delhi for talks with Indian leaders including Prime Minister Modi.
