Brother and sister William and Katherine Winter are becoming impressive linguists at a young age.

William, 13, passed his GSCE German exam with an A star grade when he was just 12, and now his sister Katherine, 12, has done the same - taking the language exam aged 11.

Both spent six years of their lives in Germany where their father, Keith Winter, worked as an accountant.

Since returning to England a few years ago, both children kept up their knowledge of the German language through academic study.

Their mother, Susan Winter, said: "Although they were surrounded by German people when we lived there, we think they have both done well. We are very proud of them. Katherine is keen to gain a GCSE in French."

William and Katherine attend Bicester Community College, and the family live at Severn Close, Bicester.
