I can’t find much info online but judging by the “Coming Up” previews in local bulletins posted to YouTube, I’d guess that Daniel Gibson presented his final edition of Prime7 News at 6.30 last Friday night.
The Openers for Prime7 Local News have been updated to Kenny/Liz versions (along with a new shot of Karl Lijnders for consistency), so I guess that confirms the presenter change:
Edit: Appears to be a temporary change for three months. No idea what Dan is up to during that time though!
