Meghan Markle's sister, Samantha, arrives in London after "promising to confront the Duchess

Half-sister Samantha, an ex-sister of Meghan Markle, arrived in the UK after promising to confront the Duchess about the health of their father, Thomas Markle.

Samantha Markle tweeted that she "was having a wonderful time in London" a few days after her reporter declared herself determined to arrange a meeting with Meghan.

The outspoken 35-year-old wrote on Twitter: "Have a wonderful stay in London! The British were so adorable and helpful!

"If I can survive the roundabouts, it will be a LOL miracle!"

His press officer, Rob Cooper, said earlier this week, while Mrs. Markle was in Italy, that she would be going to Britain, "like it or not."

He tweeted, "Samantha Markle is coming to the UK. After many private attempts to arrange an individual meeting with the Duchess of Sussex to discuss the health of their 74-year-old father, Kensington Palace refused to answer.

"I'm afraid Meghan is not aware of these quiet attempts and, therefore, making this audience public is the only option we have left.

"Currently, I have Samantha in Europe with only one short flight.

"It does not have to be public, we would prefer it to be private, Samantha is coming to the UK this week, like it or not."

Markle, who has not seen Meghan for more than a decade, often criticizes her sister and has previously said she can do more to help her father.

Mr. Markle stopped attending the royal wedding earlier this year after suffering a heart attack. He claims since he told Prince Harry, during a phone call, that "it would be better for you if I was dead".
