U.S. President Donald Trump, former President Barack Obama and British Prime Minister Theresa May have not been invited to the wedding of Prince Harry and Meghan Markle on May 19, royal and British government sources said on Tuesday.

Harry, grandson of Queen Elizabeth II and younger brother of Prince William, will marry Markle, an American actress best known for her role in the TV series "Suits," at St. George's Chapel in Windsor Castle.

"It has been decided that an official list of political leaders — both U.K. and international — is not required for Prince Harry and Ms. Markle's wedding," said a spokesman for Kensington Palace, the official residence of William and Harry.
