One is the logo of a new body designed to turn the Labour Party's new membership into an effective campaigning body. The other was the symbol of the stormtrooper group which protected Nazis at rallies and organised the disruption of opponents' meetings.

PR companies are usually paid handsomely to think up original and eye-catching logos.

So it came as a surprise when Jeremy Corbyn's party revealed its red, white and blue logo for the Labour Organising Academies group.

It bears a striking resemblance to the badge of the Nazi Party's Sturm Abteilung paramilitary wing.
