lo-fi librarian in the U.K. reports that:
Parliament.uk now offers RSS feeds for a number of their pages, but they are strangely hidden. If you sign up for the email alerts that are offered on various sections of the site, e.g. Forthcoming business, then the first email you receive will be a confirmation that also offers the RSS option. You can add this to your chosen reader and then cancel the tiresome email alerts. Convenient and convoluted all at the same time.
