Why was Meghan Markle nicknamed “Duchess Difficult”? British newspapers claim royal staff members gave her the unflattering moniker because of how demanding she is. The reports come as a second member of Meghan’s staff has quit. Samantha Cohen, who has acted as a trusted aide and private secretary to Meghan and Prince Harry, will leave her post in the spring after Meghan has her baby. Another one of Meghan’s assistants, Melissa Touabti, left after just six months on the job.
