Meghan Markle's sister Samantha turned away from Kensington Palace after arriving unannounced

Meghan Markle’s half sister reportedly clashed with security as she turned up at Kensington Palace to confront the royal.

Pictures published in the Mirror appear to show Samantha Markle arriving uninvited at the home the Duchess of Sussex shares with Prince Harry – then being turned away by security.

According to the newspaper, the 53-year-old argued with police guarding the palace gates before handing over a letter for her half sister.

The confrontation came on a recent trip to the UK by Samantha Markle which she reportedly made in order to confront Meghan.

Accompanied by her partner, who pushed her in a wheelchair, she reportedly refused to leave the palace area and went on to buy souvenirs including masks of Meghan and Harry.

According to the Mirror, Samantha Markle had given palace officials an ‘ultimatum’ in which she said she would show up to confront her sister if they did not arrange a meeting.

The source reportedly said: “She fully hoped they would let her in but she was turned away. She handed a letter to one of the guards in the hope they would pass it on. It was a sad sight.”

Since her visit, Samantha Markle has posted a series of tweets about the trip to London, including a sarcastic post featuring a clip from Monty Python.

She also made comments about being followed by paparazzi while in the UK.

During the same trip to the UK, Samantha appeared on Jeremy Vine’s Channel 5 show where she apologised to Meghan.

She said she and her father Thomas would still have been hurt and not being invited to the star’s wedding to Prince Harry, but the situation wouldn’t have “snowballed”.

She said: “I just think that families can be this way when there’s confusion and when people are hurt.

“So moving forward I apologise and I wish things could be different.”

Samantha, Meghan’s half sister from her father’s first marriage, has previously called the royal “cold” and fake.
