Catholic cardinal criticises gay marriages plan

The government's plans for gay marriage have been criticised by the most senior Roman Catholic cleric in Britain.

Cardinal Keith O'Brien, the leader of the Catholic Church in Scotland, said the plans were a "grotesque subversion of a universally accepted human right".

He said the idea of redefining marriage, which David Cameron has said he supports, would "shame the United Kingdom in the eyes of the world". Robert Piggott reports.
