Piers Morgan questions Princess Diana’s brother’s explosive claims about King Charles after error about him

Piers Morgan says Charles Spencer's public apology isn't enough.

The British broadcaster told Fox News Digital he is still pursuing legal action over what he calls defamatory passages in Spencer's memoir, "Swan Song: Diana, My Sister," even after Spencer acknowledged a factual error and apologized.

"He's published an egregious defamatory lie about me, and that lie remains in copies of the book being sold all over the world, including the United States," Morgan told Fox News Digital.
