Said Ferjani - Ennahda political party, Tunisia

Tunisia is the first Arab nation to be transformed by people power but how successful has the transition to democracy been?

Stephen Sackur talks to Said Ferjani who is a key figure in the Ennahda Movement - the moderate Islamist political party which dominates the democratically elected Tunisian government.

Ennahda says it is committed to building a Muslim democracy.

Is Tunisia a model which the rest of the Arab world can follow?
