General Debate statements

64 statements to the General Debate since 1961, 187,389 words in all. The longest was 1971, at 7,683 words, delivered by Mr. PRATT.

Of the 32 statements since 1994 whose speaker’s post the record gives: President ×16, Minister for Foreign Affairs ×10, Vice-President ×2, Minister for Foreign Affairs and International Cooperation ×1. Earlier years are excluded because UN records do not consistently identify a speaker’s post before 1994, and counting those years as though they did would make any state look as though it sent nobody senior.
