Alice Baxter in for Ros Atkins. Kasia Madera in for Zeinab Badawi.
Alice is popular with World News viewers, apparently.
(I know this is late, but oh well..) I agree with them, I think Alice is excellent. She is so enthusiastic about the headlines, and, on the 5am hour in the UK, is much more refreshing than the usual. And those hand gestures? I find them engaging, and welcoming. She even says hello welcome and to the audience, which can't be said for some other presenters, which makes their presentation seem hostile. In fact, the best World News bulletin presenters are Alice Baxter, Nik Gowing, Tim Willcox, David Eades, and Geeta Guru-Murthy.
