Fiona has had next to no experience in a rolling news format, having hardly ever done any News Channel shifts, so we don’t know how good she would be at handling all the different items and making off the cuff remarks and filler bits

I think that’s slightly unfair as Question Time involves some of those skills. Where she’s fine. And of course the likes of Dimbleby and his brother Dimbleby and their father Dimbleby presumbly hadn’t presented rolling news before they started, on the basis the BBC didn’t do rolling news.
