The Evolution of Political Interviews

As a report from the National Audit Office today concludes that severance pay at the BBC provided poor value for money and put public trust at risk, we ask what measures are being put in place to restore confidence.

With just over a year to go before Scotland votes on independence, Steve Hewlett discusses how papers and broadcasters will decide agendas, stimulate interest on both sides of the border, and in the BBC's case, ensure impartiality.

And following the death of Sir David Frost, we ask whether his interview style would work today, in an age of spin, 24 hour news coverage and news pools.
