evidence: Who is right in the territorial dispute between the Philippines and Malaysia over Sabah is a question best not asked. In answer, each side will reaffirm their absolute sovereign claim to Sabah, on the northern part of the island of Borneo, and mutual recriminations will result. [...] During the 2016 Philippine presidential campaign, one prominent candidate, Jejomar Binay (who ended up losing badly) promised to pursue the Philippine claim to Sabah. As expected, Kuala Lumpur was far from pleased. [...] Last weekend, the Malaysian Ministry of Foreign Affairs strongly criticised repeated comments by "Nene" Pimentel Jr that Sabah should be recognised as a federal state of the Philippines. Pimentel is a senior member of the consultative committee in the Philippines appointed by Duterte that wrote the draft federal constitution now tabled in Congress, and founder of the ruling PDP-Laban party. Duterte is the party chairman.
