Which of the following countries does not have English as it's "de jure" official language?

As of 2019, there were 55 sovereign states and 27 non-sovereign entities where English was an official language. Many country subdivisions have declared English an official language at the local or regional level.

The majority of states where English is an official language are former territories of the British Empire. Notable exceptions include Rwanda, which was formerly a Belgian territory, Cameroon, where only part of national territory was under British mandate, and Liberia, the Philippines, the Federated States of Micronesia, the Marshall Islands, and Palau, which were American territories. English is the sole official language of the Commonwealth of Nations and the Association of Southeast Asian Nations (ASEAN). English is one of the official languages of the United Nations, the European Union, NAFTA, African Union, Organisation of Islamic Cooperation, Caribbean Community, Union of South American Nations and many other international organisations.

The United Kingdom, the United States, Australia and New Zealand, where the overwhelming majority of native English speakers reside, do not have English as an official language de jure, but English is considered to be their de facto official language due to its dominant position in these countries.
