Here's what we found: The U.S. State Department keeps
records of visits from foreign leaders, but these are not complete prior to 1929. Nonetheless, according to this data, no U.K. prime minister has
visited the U.S. on Inauguration Day since 1929, and so would not have attended the event. Records from the
National Archive in the U.K. show no evidence of prime ministers attending U.S. presidential inaugurations since the Office of the Prime Minister was established in 1916. No photographic evidence in the picture archive
Getty exists of U.K prime ministers attending inaugurations between 1877 (the first inauguration since foreign leader visits to the U.S. were first
recorded in 1874) and 1929, when complete U.S. records
began. Therefore, we rate this claim true, from at least 1929 to 2025.
According to the State Department Office of the Historian, the first U.S.
visit by a U.K. prime minister was from James Ramsay MacDonald, from Oct. 4-10, 1929. President Herbert Hoover was
inaugurated on March 4 of that year, seven months before MacDonald's visit. U.K. prime ministers have visited the U.S. in 21 inauguration years since 1929, including that year. None of these visits overlapped with Inauguration Day (March 4 in 1929 and 1933, Jan. 20 since then). The closest a U.K. prime minister has come to visiting on Inauguration Day was Theresa May in 2021, who
visited the U.S. on Jan. 27, 2017, one week after the first
inauguration of President Donald Trump. The U.S. State Department has
recorded visits from every consecutive U.K. prime minister since Clement Attlee, who visited in 1945. Even Liz Truss, who held the post for
just 45 days in 2022, managed to squeeze in a
visit.
The State Department also has incomplete records prior to 1929. Nine inauguration years are missing from records between 1874 and 1929. A further five inauguration years (
1881,
1909,
1913,
1921 and
1925) are recorded but without visits from a U.K. prime minister.
Trump has bucked tradition on Inauguration Day invites, according to
reports, by inviting several foreign leaders, including China's President Xi Jinping. Other notable guests include TikTok CEO Shou Chew, who is expected to attend, according to Trump transition
officials cited by NBC, the day after the video-sharing app will likely be hit with a
ban in the U.S.
