The couple could be seen making a series of extraordinary claims – from Harry stating, "They were happy to lie to protect my brother. They were never willing to tell the truth to protect us", to Meghan claiming, "I wasn't being thrown to the wolves. I was being fed to the wolves."

A large number of social media users have suggested it will mark the end of the couple’s relationship with the royal family. "Well, everyone. I think this will be the final nail in the coffin for any possible future family relations…" one wrote on Twitter.
The second part of Harry and Meghan's Netflix series lands on Thursday 15 December – the same day as the Princess of Wales' Christmas Carol Concert at Westminster Abbey.
