Tom Buckham and the team at Future Radio in Norwich have already had a sneak preview of covering politics when the Norwich North seat was vacated. This was due to the resignation of Ian Gibson after being banned from standing as a Labour candidate for the next general election. So, already a possibly thorny situation.
You can see how they publicised the invitation to come on the station and how they handled interviewing all the prospective candidates who replied.
All candidates were invited to the station and whether they went or not, were listed on the website.
You can access the dedicated page for the by-election at the Future Radio website where all the interviews are available as podcasts.
