Well, I was expecting something similar to occur to detract from the Windrush scandal and all the other mess-ups that are happening.
I think these sorts of accusations are best ignored - they are becoming so predictable now. Certainly someone like Corbyn, who has actively campaigned about racism all his life and who protested against apartheid when Mrs Thatcher was referring to Nelson Mandela as "a terrorist", would never condone racism. However, if such comments have been made, who's to say that these people are real Corbyn supporters? They would hardly be doing Corbyn any favours in making comments such as have been reported. They are an absolute gift to Conservative Party Central Office which has wasted no time in calling out its troops to express their outrage and pin the blame on Corbyn.
