Prince Harry and Meghan Markle's titles could have a "question mark" hanging over them if they are seen to be "tarnishing" the monarchy, a royal expert has said.
The couple has given several interviews where they have criticised their royal relatives and the institution - especially in their bombshell chat with Oprah Winfre y last year. Now Harry's father Charles is King, Harry and Meghan's children Archie and Lilibet are entitled to be known as prince and princess as they are the grandchildren of the monarch. But according to royal author Katie Nicholl, if Harry and Meghan continue to speak out about their relatives, Charles could unleash his "ruthless side" leaving their titles as well as their children's in doubt.
