Last week the whole of Europe heard a howl of rage coming from Catalonia. Since Spain’s highest court sentenced nine pro-independence politicians to a collective one hundred years in prison there have been mass, sometimes violent protests across the region which has left hundreds injured.

What will become - what should become - of Jack Letts? HARDtalk's Stephen Sackur speaks to his parents, Sally Lane and John Letts.

She risked everything, including prison, in an act that changed her life. Now her story has been made into a movie; but, 16 years on, has her perspective changed?
