The difference between him and Moira is, as mentioned, Moira didn't have that skillset and was hired as a newsreader and announcer and nothing else - which is a job that doesn't really exist anymore.
That role still exists in radio of course, she'll be fine on Classic FM, and a lot better than some truly awful voices/styles I hear on other commercial radio stations.
I wonder how Moira worked when at Radio 2 (and indeed how she will now at Classic)? Would she have been involved in writing the bulletins or as not qualified did she literally just read them out? I'd have thought Global would be a bit more restricted in their newsgathering resources, meaning surely it doesn't make economic sense to employ someone to just read the bulletins?
Pretty sure Global will have more than one duty newsreader/presenter. Even if a presenter has written all the scripts then reads them out for one station, Moria can read those same scripts for Classic. I also wouldn’t be surprised if she tweaks them slightly (bit not editorially) to make them scan “in her style” (most presenters do).
There's a lot of sharing between the stations at Global. While each station has their own presenting team/style and preference for stories, the news on all of them operates under the 'Global Newsroom' banner and shares resources accordingly. Between London and the regional sites there's a whole team of journalists preparing the stories and writing the scripts, so Moira will definitely have pre-prepared content ready for her to tweak as appropriate and read out.
As for employing people just to read the news, when it comes to the national brands operating out of London there's quite a few people who's only job is to read it. I visited Global HQ a couple years ago, and had the pleasure of sitting in the Classic FM studio while the late Alastair Yates read the news. He just read the scripts straight from the computer, and once he did that he popped next door to the Smooth Radio studio and did the same again. The regional sites are different matter as they are more restrained in terms of resources.
I love Moira's smooth voice and her Sunday night series on Radio 2, which was the only thing I listened to on that station. I'm pleased she's joining Classic FM as I ditched Radio 2 a long time ago (RIP the Togmeister). I wonder what will happen to Bill Overton?
The irritating thing about Global Radio's stations though is they keep saying who they are, e.g. "This is Classic FM......from Global".
