You may be interested in a a new website that has just launched.
http://www.britishpoliticalspeech.org/ has been created as part of an academic research project, archiving political speeches (at present many are leaders' speeches to party conference, the oldest from 1895.
The long-term goal of the site is to raise interest in, and understanding of political speech and rhetoric, especially among academics, politicians and political commentators; to promote discussion about what makes a good or a bad speech and what might make British political rhetoric better.
Users can leave comments on the speeches, perhaps recollections of seeing them delivered or critical comment about their form and content.
There is also a facility allowing people to ‘donate’ speeches so that the archive can become a truly comprehensive record of the many modes of British Political Speech.
Please make use of the site and feel free to forward information about it.
