When Tiger Woods stood up and publicly apologised for his private behaviour, he knew he was taking arguably one of his greatest risks to date. He is not the first: Confessions by public figures are commonplace today, frequently just before or just after an expose by journalists. But do they work?

Sir David talks to Sandra Scott, a psychiatrist who frequently deals with traumatised celebrities put through the mill of various reality TV shows, and Steven Williams, the boss of Midas PR, one of London's top PR agencies.

Plus, for the first time in nearly 40 years, a Cuban political prisoner starved himself to death this week.

Orlando Zapata Tamoyo died in hospital, 85 days after he began refusing food. In a rare move, President Raul Castro said that he "regrets" the death. But - as so often - he laid the blame, somehow - on the US. So what can we glean from the signals from Havana?

Sir David talks to Irenea Renuncio, a Latin America political analyst.
