Pupils were asked to imagine how it felt to be imprisoned without access to a fair trial and then express their feelings in the form of a poem, but without using traditional writing materials.
Kate Allen, director of Amnesty International UK, said: “The judges were impressed by the innovative ways in which pupils across the country took to the task and really put their minds into how individuals could continue to express themselves given limited resources.
“Aditi’s entry illustrates that perfectly. Using the tiniest scrap of paper she managed to produce a truly moving poem.”
The competition was inspired by the experiences of Irina Ratushinhskaya in the Soviet Union, Jack Mapanje in Malawi and a number of detainees at Guantanamo Bay.
