  • 31 August – Cutbacks across the BBC and at the channel result in BBC Parliament being relaunched as a channel which only provides uneditied live and recorded coverage from Westminster and the devolved chambers.

The cutbacks also see the cessation of BBC Parliament's bespoke highlights programmes The Day in Parliament and The Week in Parliament.
