On the 30th of September 1938 he stood up in Parliament and he said we will not appease Hitler. "I’m looking across to Nelson Mandela who will not give into apartheid. And today we say ‘We will not give in to the ERG’.” And when quizzed over his “unacceptable comparison”, he responded: “Andrew, I would say that it was not strong enough. In 1938 there were allies who hatched the plan for Hitler to annex parts of Czechoslovakia and Churchill said no, and he stood alone. We must not appease. “We’re in a situation now - and let me just be clear, I’m an ethnic minority - we have in the ERG and in Jacob Rees-Mogg someone who is happy to put onto his web pages the horrible, racists AFD party.
