Meghan Markle's Sister Arrives In London, Reportedly Threatening Royals For More Embarrassment

Meghan Markle's sister now in London.

The Duchess of Sussex's controversial half-sister, Samantha Markle, has arrived in the royal family's playground. She confirmed this in a post on Twitter. "Having a wonderful time in London! British people have been so lovely and helpful! If I can survive the roundabouts it will be a miracle LOL!" Samantha wrote.

Danyal Hussain of Daily Mail, however, has claimed that she is there for nefarious reasons. Samantha is reportedly threatening more embarrassment for the royal family. She reportedly vowed to have a "showdown with the duchess over their father's failing health."

Prior to Samantha's arrival in the UK, her PR manager, Rob Cooper, announced her intention on social media. According to Cooper, Samantha is hoping to meet Markle to discuss their father's poor health after the royals continue to ignore them.

"I fear Meghan may not be made aware of these discreet attempts and therefore making this public is the only option we have left. I currently have Samantha in Europe with just one short flight away. This DOESN’T need to be public, we would prefer to keep this private. Samantha is coming to the UK this week, like it or not," Cooper wrote.

However, Samantha is unlikely to convince Markle to meet her. According to a source close to Prince Harry's wife, the former "Suits" actress has no plans on meeting her sister whom she hasn't seen for years already.

"Samantha is kidding herself if she thinks there is any possibility of getting together with Meghan, or anyone from the Royal family for that matter," the insider said. "Meghan and Samantha are not close in the slightest. They never have been and it's doubtful they ever will be, especially after all of Samantha's name-calling and bullying."

Samantha has been posting numerous tweets attacking the Duke and Duchess of Sussex. Earlier this month, Samantha took to Twitter and questioned Markle's humanitarian effort while ignoring their dad.

"I am not candy coating anything anymore! The DUCHASS should be humane to our father who has given her everything,.. and this media crap can stop! He was the one who was always there for her. Fake waves and smiles can stop. The duchASS can bow to the daddy," Samantha wrote on Twitter.
