To keep it brief - A and B are named executors of the will of C. The will has been in place for over 10 years. A is C's adult child, B is a long standing and valued friend (not a family member).
Sadly, C passed away very recently. The funeral is yet to be organised.
A has since contacted B telling them that they are "relieved of the need to be executor of the will, and that A will deal with things as necessary", and effectively saying that C's affairs are a family matter and none of B's business. B is upset, as they made a solemn promise to C that they would ensure their affairs were properly and fairly sorted out. B feels that C asked them to be executor as they didn't trust A to do the job properly. B has not seen the will, but knows it is lodged with C's solicitors and has their contact information.
So - can an executor "sack" a fellow executor in this way, or should B contact C's legal advisors to ensure that are fully included in all decisions regarding C's estate. As far as B knows, they are not a beneficiary of the estate and will simply be acting out of long standing loyalty to their old friend.
