Angela Levin also claimed the visit is "badly timed", adding the couple are "trying to grab a few shots that will help them with their Netflix career".
However, royal commentator Emily Andrews contended the Queen's invitation will "hopefully be not only an olive branch", but also provide a "rapprochement within the Royal Family itself".
