Catholic synod: Family values top the agenda in Rome

Marriage, divorce and contraception will top the agenda at the extraordinary Catholic synod in Rome where leading clergy are gathering on Saturday.

Family values are some of the most hotly-debated issues in the Roman Catholic Church.

Millions of Catholics around the world will be watching closely to see what signals the Vatican is sending about the future of family life.

The synod is seen as the litmus test for Pope Francis' papacy, which may well be judged on the outcome.

The BBC's Religious Affairs correspondent Caroline Wyatt reports from Rome.
