The Shadow Chancellor just quoted one of history's most brutal dictators in the House of Commons
In his response to chancellor George Osborne's Autumn Statement speech, McDonnell took the bizarre step of reading from Mao's 'little red book', before throwing it across the Commons despatch box towards Osborne, and prime minister David Cameron.

We must esteeem them as teachers, learning from them respectfully and conscientiously, but we must not pertain to know what we do not know. I thought it would come in handy for him [Osborne]."
