Can an Administrator step down

We have an intestacy where the application has been made for the LoA but not yet issued. One of the relatives who has applied and has been active in the administration so far now wishes to step down as an administrator (before the grant is issued).

If he were an executor I would have no doubt that he has intermeddled but does that follow through to an administrator - I cant see that it would.

Do I just contact the PR and cancel the application?
