An extraordinary collection of patriotic First World War recruitment posters have been unearthed after 100 years stashed under the stairs of a pensioner's Brighton home.

In total, 10 morale-boosting posters were found - all of which belonged to an elderly former airport worker now in her 90s.

The haul was discovered as part of a house clearance. The colourful posters had been stashed under the stairs of the woman's house for many decades
