A lieutenant governor is a high-ranking government official who serves as the second in command to the Governor of a state or province. The specific duties and responsibilities of a Lieutenant Governor vary depending on the jurisdiction, but generally they are responsible for overseeing the day-to-day operations of their office and representing the Governor at various events and functions. In some cases, the Lieutenant Governor may also have to step in as acting governor if the Governor is unable to fulfill their duties or resigns from their position.
