Civil Partnerships, Marriages and Deaths (Registration Etc.) Bill

The consultation did not have any consensus that we should go down the civil partnership line, but will my hon. Friend comment on the fact that in France, religious marriages are not recognised and have to be preceded by a civil ceremony? I wonder whether any data have been gathered about how many split-up families they have there, or whether they have a better record than we are likely to have, because this is really all about family stability.
