I posted this to the Benefits News (green section on left of page)section myself yesterday, however the Moderators do not have "approval" rights on that page, so I assume it is still in the queue to be published.
The documentary will disappear off i-player in a couple of days and now my post and link has gone again.
For anyone interested, the link to the programme also appears at the bottom of the Disability Alliance page in the news item about a different proposed radio 4 documentary.
