Traditionally, the 1st speaker at the United Nations Basic Assembly is from Brazil, followed by the host nation. This tradition started when Brazil stepped forward as the 1st speaker in the early days when no nation volunteered for the part. More than time, it became typical for Brazil to initiate proceedings.
Right after Brazil and the host nation have spoken, the leaders or representatives of all other nations take their turn to address the assembly. They have the capacity to speak any of the six official languages of the UN: Arabic, Chinese, English, French, Russian or Spanish. Even though speakers are advised to limit their speeches to significantly less than 15 minutes, this guideline is generally overlooked. Notably, Cuba’s Fidel Castro holds the record for the longest speech, which lasted 4 and a half hours, provided in 1960. Thankfully, we never anticipate similarly lengthy speeches now.
As a rough estimate, we anticipate President Biden to contact about 9:45 ET / 14:45 BST, followed by President Zelensky about 12:45 ET / 17:45 BST. Nonetheless, it is worth noting that these terms are topic to adjust, as they generally are.
