trying to order breadcrumbs on single post page

Hi

I am using this:

<?php the_category('&raquo', 'parents' ); ?>

And it outputs like this (eg):

Employment Law Factsheets» Factsheets

But that is alphabetical and I want it to list hierarchically like a breadcrumbs. So how do I do that so it outputs like this?

Factsheets » Employment Law Factsheets

Thanks!
