Tomorrow at 12.30 we have a Twitter Q&A with Holocaust survivor Harry Olmer BEM, recommended for ages 13+. Harry came to the UK as part of the group of child survivors known as 'the Boys'.

Please send us in your questions here or using #Harrylive.

Before coming to the UK Harry had been forced to work in the Płaszów labour camp, and then to Skarżysko-Kamienna, where he was forced to fill shells and land mines with acid for the German HASAG company.
