Made In Chelsea star Oliver Proudlock has apologised after he appeared to reference the Holocaust in an Instagram selfie.
The 32-year-old said he was "mortified by his actions" after he posted a photo from his holiday in Greece captioned: "Boy in the stripe pyjamas."
Many linked the caption to The Boy In The Striped Pyjamas, a book set in a Nazi concentration camp during the Second World War.
The 2006 novel, written by John Boynes, was adapted into a film in 2008 starring Asa Butterfield, Rupert Friend and David Thewlis.
In it, Bruno (Butterfield), the eight-year-old son of a concentration camp commandant, forms a friendship with a Jewish boy he meets across the camp's fence.
Proudlock apologised, writing on his Instagram story: "I have a massive apology to make regarding a caption in one of my stories yesterday.
"I have hurt a lot of people with my badly chosen words and I am so, so sorry. It was incredibly ignorant.
