have to/must

"We have to and must change that." (Jeremy Corbyn.)

Is there any difference in meaning between "have to change" and "must change" in the above sentence?

Thank you.

I think Corbyn used the two to emphasis the idea of obligation.

Piscean, would you care to correct your sentence? ;-)

Thank you, Piscean, for your reply.

Could you agree with my interpretation of that: "have to change" means the external obligation and "must change" the internal one?

I've read it as "he has to change things because there is a popular demand for change thus forcing the Labour leader to do that" and "he must change things because of his own will and determination to do that".

Is my interpretation far-fetched?
