The Landlords Union is at the centre of a Twitter storm after using an image of Auschwitz on a press release.
The blunder appeared around two weeks ago on a story about new government powers set to come into force in April, but the photo was only changed today.
The article centered on new regulations that would see rogue landlords with criminal offences of blackmail, theft, handling stolen goods, harassment and stalking banned from renting out property.
But accompanying the release was a picture of what appears to be Auschwitz-Birkenau, the largest Nazi concentration camp where 1.1 million prisoners, who were mostly Jews, died.
A post with the same image also appeared on Twitter, with the picture showing buildings surrounded by barbed wire.
Underneath the Twitter post, Marcopolo wrote: ‘Was wondering how it relates to their article.’
While wexfordkate added: ‘Well, indeed. It’s quite shocking.’
1.1 million Jews, Romani, Poles, Russians and other minorities were killed at the Nazi’s Auschwitz-Birkenau network of extermination and concentration camps in Poland.
Hitler ordered the construction of the concentration camp in Poland a year after German forces invaded in 1939.
The camp in its earliest form became operational in 1940, and only liberated on January 27, 1945, by the Red Army’s 322nd Rifle Division.
The death camp was initially intended to hold Polish political prisoners, though it was later handed over to the SS.
Jewish men, women and children were slaughtered in gas chambers, through starvation, beatings or even being worked to death.
The Landlords Union says it specialises in landlord tax and shares best practice among UK landlords.
The photo has now been removed from the story. The Landlords Union has been contacted for comment.
