A primary school head teacher has apologised after pupils were allegedly told to slant their eyes to make them "look Chinese" for a class photograph.

The six and seven-year-olds, who were working on a project about China, were dressed in Chinese clothing when they posed for a group picture.

They were asked by a teacher to pull up the side of their eyes, parents claimed, before the photo was taken.

The unnamed teacher and a teaching assistant were also in the picture, which was later pinned to a window of New Bradwell School in Milton Keynes, Buckinghamshire.

The school has now apologised and launched an investigation.
