New Delhi: Political clearance would have to be sought by those invited by Pakistan to the inaugural ceremony of the Kartarpur corridor, MEA said on Thursday, a day after Pakistan Prime Minister Imran Khan invited Congress leader Navjot Singh Sidhu to the inauguration.

"I think the political personalities or invitees who think they need to get a political clearance, and those not included in the list will know about it. There won't be surprises," the Ministry of External Affairs spokesperson Raveesh Kumar said.
