Long sentences confuse the listener and leave the newsreader gasping for breath before reaching the relief of a full stop.
Break long sentences into two sentences if it reads better.
If a point needs explaining, do that in a separate sentence.
Use verbs (“murdering”) rather than nouns (“the murder of”).
“A man has been charged with murdering his wife”
is better broadcast style than
“A man has been charged with the murder of his wife.”
