At a Labour Party fundraiser in Cheadle, Cheshire, Dalloul al-Neder went up to speak about the plight of Palestinians in Gaza.
Five of his family died in bombing in December.
The response from Labour Party Deputy Leader Angela Rayner and Shadow Business Secretary Jonathan Reynolds was to show contempt and allow Dalloul to be physically assaulted by a member of the police force.
Here Dalloul and fellow protester Natasha Khan reflect on what happened.
