Ireland correspondent Chris Page looks at the growth of Sinn Féin across the island of Ireland over the last 30 years and explores how it has achieved that. He examines the party's current aims and policies, from housing to the economy. And he asks, given the current trend in the polls, what the implications might be of the party being in government in two jurisdictions - in Belfast and in Dublin.
