Two of Iran's main opposition leaders are in their 70s and in poor health but 23 months of house arrest have failed to crush their "unshakeable spirit", their families said last week.
Mir Hossein Mousavi and Mehdi Karroubi are standing by their "righteous and principled position", they added in a statement that demanded their immediate release. That position is primarily a call for the "ruling apparatus" to recognise "the people's right to self-determination".
Cut off from the outside world, the two men --- along with Mr Mousavi's charismatic wife, Zahra Rahnavard - have been denied free access to newspapers, television, the internet and regular family visits.
But all three are now back in the Iranian spotlight ahead of polls in June to elect a successor to President Mahmoud Ahmadinejad.
