WATCH: Prince William reacts to questions about Charles Spencer's Diana book

Prince William’s latest outing in London coincided with the release of Charles Spencer’s book on his mother, the late Princess Diana.

According to Kensington Palace, the Prince of Wales visited Act One Cinema, an independent community venue bringing people together through film.

Reported asked Prince William how he feels about "Swan Song: Diana, My Sister", a book written by his maternal uncle. Some reporters shouted questions whether he had read the book.

However, William remained silent and entered the theater without answering any questions.

The book about Princess Diana contains contentious claims about William’s father, King Charle.

Buckingham Palace hit back immediately, saying the king was "mindful that the pain of fraternal grief can cloud reason, judgment and memory", as it sought to prevent the king from being dragged back into one of the royal ⁠family's most damaging periods.
