What to expect from King Charles' Congress speech

King Charles, who's set to travel to the US later this month, has been formally invited to deliver an address before a joint meeting of the United States Congress.

The 77-year-old will share his vision for the US-UK special relationship. The engagement will mark the King's inaugural State Visit to America since ascending to the throne.

James Michael Johnson, speaker of the United States House of Representatives, has invited the British monarch to address a Joint Meeting of Congress.

Prince William and Harry's dad is expected to speak on Tuesday, April 28, during his forthcoming visit to the American capital.

The speech will take place in Washington, DC. The timing of the King's congressional appearance carries particular resonance, coinciding with America's celebration of 250 years of independence.

In his letter, Johnson acknowledged that the bond between Britain and America represents "one of the most consequential partnerships in modern history."

He noted this relationship extends beyond mere shared interests, invoking the late Queen Elizabeth II's 1991 address to Congress in which she spoke of a shared "spirit of democracy."
