David Cameron: UK 'junior partner' to US

David Cameron has been criticised after mistakenly saying the UK was the "junior partner" in the allied World War II fight against Germany in 1940.
He made the historical slip, neglecting the fact that the US had yet to enter the war, on the second day of his first trip to the US as prime minister.
Labour's David Miliband called it a "slight", while a veterans' group said it could "alienate" former troops.
