"That bloody woman" - that's how Prince William is said to have described his sister-in-law Meghan Markle.
The alleged description comes in a dossier from Robert Lacey, a communications chief at the Palace.
Prince William is said to have been left seething after claims of bullying emerged against Meghan, BirminghamLive reports.

In his Battle of the Brothers book Mr Lacey writes: “According to one of my sources, it's been pointed to him that everyone has a difficult sister-in-law.
“William's response was to nod his head in sage acceptance. Then suddenly he broke out angrily. 'But look at the way that bloody woman treated my staff — merciless!’”
Mr Lacey adds: “Sussex supporters have noted the bizarre combination of self-promotion and self-pity that characterises Meghan, and can see why it has infuriated William.
“’Meghan can be a 500 per cent nightmare,' some close friends of Harry are among the first to admit.
"The never-ending PR. She's just so . . . American!'”
After reported tension between Prince William and Prince Harry, they are due to unite on July 1 for a memorial to their late mum, Princess Diana.
