One in five young British children cannot find the UK on a map of the world, a magazine’s research suggests.

National Geographic Kids said it also found fewer than two thirds of children were able to correctly locate the US.

The magazine, which questioned more than 1,000 six to 14-year-olds, said it discovered several children in London did not to know it was the UK capital.

But the National Association of Schoolmasters Union of Women Teachers branded the findings as "nonsense".

National Geographic Kids also revealed 86% of the children interviewed failed to identify Iraq and that the boys had slightly better geographical skills than the girls, with 65% being able to locate a number of countries around the world compared with 63% of girls.

Scottish children fared better with 67% able to identify the most countries on a world map.

The magazine carried out the study to mark its UK launch and highlight "gaps in children’s geographical knowledge".
