Their arms raised in a Nazi salute, two young tourists pose alongside a waxwork of Adolf Hitler.
This was the sight which greeted an Israeli couple on a visit to Madame Tussauds in London.
The couple, whose grandparents survived the Holocaust, photographed the incident and complained about the tourists' behaviour, which they described as 'an unequivocal demonstration of anti-semitism and bigotry'.
But while Tussauds apologised for any offence caused, it insisted: 'We proactively encourage our visitors to interact with the waxworks should they so choose.
'We absolutely defend the right of our visitors to make such choices for themselves, as long as they behave themselves responsibly.'
Its comments were described as appalling and insensitive by Lord Janner, chairman of the Holocaust Educational Trust.
The unnamed couple, who live in London with their baby son, visited Madame Tussauds this month, joining the crowds of summer tourists queueing to see waxworks of celebrities including David Beckham, Kylie Minogue and the Royal Family.
They described the figure of Hitler as 'extraordinarily disturbing'
