The Duke of Cambridge has blamed BBC failings over its interview with his mother for fuelling her paranoia and worsening his parents' relationship.

After an inquiry found the BBC fell below its standards, Prince William said he was "most saddened" Diana never learned she had been deceived.

He said his mother was failed "not just by a rogue reporter" but by BBC bosses.

The Met Police said it will assess the new report, after previously deciding against a criminal investigation.

The Duke of Sussex blamed a toxic media culture for his mother's death.

In his separate statement, Prince Harry said that the "ripple effect of a culture of exploitation and unethical practices" ultimately took his mother's life.

He expressed concern such practices "are still widespread today", adding that it was "bigger than one outlet, one network or one publication".

"Our mother lost her life because of this, and nothing has changed. By protecting her legacy, we protect everyone, and uphold the dignity with which she lived her life," he said.

The BBC has written to apologise to Princes William and Harry, as well as the Prince of Wales and Diana's brother Earl Spencer.
