Please explain me about this Future Tense?

[Surjamankhatiwora]

Hi!

This is with regard to the "Future Tense" on a story Jealousy. I don't understand what this Tense due to actually means.

A sentence from the story:
She's due to become a councillor next month after the elections and she'll probably make a good job of it.

Does it mean She's going to be a councillor next month or does it has different meaning?

[Beeesneees]

She is about to become a councillor... the plan is that she will take this position next month, everything is in place for this to happen.
