Answer:
Speaker of the United States House of Representatives (In the Case of USA as a nation)
Explanation:
The constitution of the United States stipulates that in the case both the president and the vice president can no longer serve due to death or Resignation, or Inability to discharge the Powers and Duties as required, the line of succession would fall to the speaker of the house.
However, this is different in other countries. For example, In Nigeria, when the president and vice present cannot discharge their duties, the senate’s president takes over as the president before the Speaker house of representatives unlike the line of succession that operates in the U.S
