Students from Priory School Amnesty Group in Lewes have met with Foreign Minister Alistair Burt to discuss the fate of Guantanamo Bay prisoner Shaker Aamer.
Aamer is the last British resident left in the US detention facility. The schoolchildren presented their request for the prisoner, who has never been charged, to be returned to the UK.
Lewes MP Norman Baker was also present in the meeting. Shaker Aamer has been held at the camp since 2002.
