Explosive top-secret documents suggest that England's Duke of Windsor Edward, who abdicated his throne in 1936 to marry American divorcee Wallis Simpson, betrayed his country and family by providing Adolf Hitler with vital information that led to the bombing of Buckingham Palace during World War II, the tabloid Globe claimed in its latest issue.

Following his abdication and marriage, the Duke and his wife lived in exile in France, where they became Nazi sympathizers and met Hitler during a 1937 tour of Germany. It is believed that the Duke hoped for Germany to win the war, expecting to regain his throne with Wallis as queen under Hitler's regime.

Photographs reveal the Duke reviewing German troops, visiting Hitler's mountain retreat, and even performing a Nazi salute. Leaked documents suggest that he shared intelligence that aided Germany's invasion of France.

Royal expert Alexander Larman, who reviewed classified archives, has concluded that the Duke of Windsor provided the Nazis with detailed information about Buckingham Palace's layout to assist their Sept. 13, 1940, bombing raid. The Palace was the residence of King George VI, the Duke's brother, and other members of the royal family at the time.

Larman stated, "The Nazis knew what they were doing, and that's because they had inside information from the Duke." He added, "I don't think he wanted to see his brother King George VI dead, but he was in a position where he knew exactly where everyone was in Buckingham Palace."

Nazi aircraft dropped six bombs during the raid, narrowly missing the Palace but destroying the chapel. King George's wife, Elizabeth, recalled the sound of a German plane and a bomb that "exploded with a tremendous crash in the quadrangle." The royal couple had to take cover in a corridor to avoid flying glass before making their way to an air raid shelter.

King George recounted that the aircraft had flown straight down the Mall and dropped two bombs in the forecourt, two in the quadrangle, one in the chapel, and another in the garden.

Edward's attempt to regain power failed, and he was eventually sent to the Bahamas. The disgraced Duke passed away in Paris in 1972.
