Caretaker Sabah Chief Minister Shafie Apdal has urged Wisma Putra to summon the Philippine ambassador in Kuala Lumpur after the country's legislators proposed to print a map that includes Sabah on its passports.

Shafie said Wisma Putra should give the ambassador a stern warning over the move, which he said is an infringement of Sabah's sovereignty and an unwarranted provocation.
