Protesters are gathering outside The Church of Scientology's massive new centre in Dublin today.

The leader of the secretive religion - David Miscavige - is expected to attend the opening ceremony at the centre in Firhouse - which can seat over a thousand people.

Demonstrators from Ireland and abroad have been arriving outside - many of them former members of the church which they say is a 'cult'.
