The Palestinian delegation to the United Nations is pushing for a vote to be recognised as a full member state next month, Ambassador Riyad Mansour has said, a move opposed by the United States, according to AFP.

“We are seeking admission. That is our natural and legal right,” Mansour said, adding that he was pushing for an April 18 vote at the UN Security Council.

“Everyone is saying ‘two-state solution’, then what is the logic of denying us to become a member state?” he added.

Any request to become a UN member state must first pass a vote by the Security Council — where Israel’s ally the United States and four other countries wield vetoes — and then be endorsed by a two-thirds majority in the General Assembly.

Palestinian President Mahmud Abbas originally launched the statehood application in 2011. It was not considered by the UNSC, but the General Assembly the following year granted a more limited observer status to the “State of Palestine”. The Palestinian Authority submitted a letter to UN Secretary-General Antonio Guterres asking for the UNSC to reconsider on Tuesday.
