Shadow chancellor John McDonnell came to almost dominate the news cycle last week thanks to a stunt in which he literally threw Chairman Mao's 'Little Red Book' at George Osborne after the Autumn Statement.
The move was a gift for the Conservatives, who criticised it as crass politics.
The shadow chancellor was forced to maintain that it was a joke about encouraging Chinese investment in the UK and that he takes the millions of deaths under the collectivist policies of Maoist China seriously.
In a London Chamber of Commerce and Industry event in the City today, McDonnell was asked about the by now infamous throwing of Quotations from Chairman Mao Tse-tung across the despatch box.
McDonnell responded with another communism joke, telling reporters that he would have prefered to take Karl Marx's Das Kapital, but it was too heavy.
