Saturday Night Live UK debuted on March 21, 2026, on Sky One, featuring a sketch starring George Fouracres as Prime Minister Keir Starmer. The sketch, shared by U.S. President Donald Trump on Truth Social without comment, humorously depicted Starmer struggling to handle a phone call from a Trump impersonator. It included satire on international tensions, a fictional Gen Z adviser named Starmzy, and references to political figures like Diana, Princess of Wales, and Sir Winston Churchill. The show, modeled after the long-running American series, includes monologues, topical sketches, and a UK version of The Weekend Update.
