Earlier this year, Paul Martin, a BBC film-maker and journalist, was arrested by Hamas. He spent a month in jail in solitary confinement.
He was arrested on February 14 in a court in Gaza where he had
intended to testify on behalf of a man, Mohammed Abu Muailek accused of working with Israel.

While the UK government and international organisations worked for his release, a news blackout was imposed.

Don't miss what promises to be a fascinating event: Paul Martin will talk to us about his ordeal - what it was like to be in a Hamas jail, how he was treated, and what inner resources kept him going.
