A broadcast news analyst and a newsreader are not the same thing. A broadcast news analyst is the poor soul who's usually stood at the physical location where something important is happening, and giving their own interpretation live from the scene while people pull funny faces and shout offensive words in the background. They're not just reading from an autocue - they'll have researched their questions and come up with a structure for their presentation or interview so they can get the essential facts over to the viewer in a time-pressured environment.
It goes without saying that any broadcast news analyst has to be a confident and articulate public speaker. They'll have had experience working within the industry before appearing on camera, often as an assistant to another broadcast news analyst. A degree in broadcasting is considered essential, and you'll have to be flexible with your hours and travel arrangements. When news happens, you have to be there.
