Queen Elizabeth II and her husband Prince Philip will pay their fifth state visit to Germany in June, Buckingham Palace announced on Monday.
The 88-year-old monarch and her 93-year-old husband will visit between June 24 and June 26, at the invitation of German president Joachim Gauck.
They have made numerous previous trips to Germany, including four other state visits, in 1965, 1978, 1992 and 2004, while the queen also went to Berlin in 1987 and 2000.
News of the state visit comes just two days before German Chancellor Angela Merkel visits London for talks with Prime Minister David Cameron.
The queen and her husband, the Duke of Edinburgh, have scaled back their overseas trips in recent years, allowing their eldest son Prince Charles and other royals to represent them.
Last year they attended the 70th anniversary commemorations of D-Day in France and also made a one-day trip to Rome, but before that the monarch had not left Britain since visiting Australia in October 2011.
