House Speaker Mike Johnson will travel to London later this month to address the United Kingdom’s Parliament, becoming the first sitting U.S. speaker to do so.

Johnson announced his invitation on Wednesday, saying he was “honored and humbled” to accept the invite from Sir Lindsay Hoyle, speaker of the U.K. House of Commons, ahead of America’s 250th anniversary of independence.

“The U.S. and the UK have stood together as pillars of peace and security across generations,” Johnson said in a statement. “We forged this important friendship in the great wars of the 20th century, but the true source of our strength comes from our shared commitment to individual freedom, human dignity, and the rule of law, which together form the exceptional, joint heritage of the English-speaking world.”

Johnson’s address on Jan. 20 will be one of many ceremonial events the U.S. has planned to commemorate this year’s anniversary around the country.

“As America begins its Semiquincentennial celebration, I will be happy to visit one of the great shrines of democracy itself, where the principles that launched the long struggle for American liberty were debated and refined,” Johnson added.

Though Johnson will be the first sitting speaker to address Parliament, Hoyle said he was pleased to continue a tradition from 50 years ago, when his predecessor invited then-Speaker Carl Albert to London to mark the 200th anniversary. Doing so, Hoyle added, continues to “acknowledge the enduring close relationship between our parliaments and people.”

“Our UK Parliament is sited just miles away from where the cross-Atlantic relationship began more than 400 years ago,” Hoyle said in a statement distributed by Johnson’s office. “The courage of the Founding Fathers, who set sail on the Mayflower for the New World, built a bridge and connections across the Atlantic, which continues until today.”
