It would be a great relief to us all if the palace would just carry out a full investigation, make a full statement about the racism accusations, briefing against H&M, and anything else they'd like to get off their chest. Make it clear that the Sussexes will or won't be keeping their titles, ensure us they are out of the royal inner circle, and are now irrelevant.
So they can move in with their work, if Charles doesn't decisively draw a line under this now and end it his entire reign will be plagued and overshadowed by Harry's accusations and complaining.
Times have changed, with digital and social media, stories, gossip & bullying carries on gaining a life if it's own. It's not like in the Queen's day, when todays newspapers were used to wrap tomorrows fish & chips in and stories were soon forgotten.
