The highest-level US delegation to Cuba in decades is taking part in two days of negotiations after grand promises by President Barack Obama about change on the island and a sombre warning from Cuba to abandon hopes of reforming the communist government.
It has been a week of historic diplomacy in the Cuban capital.
Tonight, the extraordinary changes taking place between the USA and Cuba are illustrated in the words of a Cuban man who is hailed as a hero in his country after being jailed in the US for spying.
He has told ITV News that he would welcome a visit to Havana by President Barack Obama.
