SIR - Barrack Obama has taken the unusual step for a former US president of criticising the current one, Donald Trump, urging Americans to wake up and vote for Democrat Biden. If the Democrats win November's election, Kamala Harris will be the first black female vice president in US history. And she has urged African Americans and women to come out and vote.

I never saw this coming. This is cutting edge stuff. I always thought Trump was a beacon of progressivism and everyone liked him. We need more blue sky thinking from our enlightened and woke politicians and commentators like this to show us the way.
