Jelllyjam, i see...
I guess you put the word "both" in the right place!
Well, the sentence was last, of course.
"I put the word "both" in the last sentence?"
Last is when smth comes in the end or stops... Latest can be news, it means that they are fresh but not last, then it will mean that there will be no news at all.
For example, his last word was... - he said smth in the end of his speech, life, etc.
The latest rumours - the fresh rumours...
Get it? ;)
Sorry if it was too hazy an explanation!
