Countering speculation that the 70-year-old is considering standing down, Corbyn told the BBC on Sunday that he would lead Labour into the next election.
Asked if he would serve a full term, Corbyn said: "Of course."
Corbyn is at Labour's annual conference in the southern English city of Brighton. The gathering has been overshadowed by an attempt by a close ally of Corbyn's to oust his deputy Tom Watson, a move that was abandoned after Corbyn intervened.
Watson has upset many of Corbyn's left-wing supporters by seeking to make Labour an anti-Brexit party.
