A memorial to honour secret agents who worked for the Allies in World War II is unveiled in London, featuring a carving of captured and executed Violette Szabo.

They came from all generations of the military - veterans of World War II, serving men and women, and young military cadets - all gathered on London's South Bank to see the new memorial officially unveiled.

The bust gazing out across the Thames depicts Violette Szabo, one of Britain's more extraordinary under-cover agents.

Daughter of a French mother and English father, Violette grew up in Brixton, South London.

But when her husband was killed fighting in North Africa, she volunteered for under-cover operations in France.
