Today Jeremy Corbyn swept to victory, increasing the size of his mandate with 61.8% of the vote, a larger margin of victory than last year.
More than half a million party members, trade unionists and registered supporters voted in the contest.
In a result announced on the eve of Labour's party conference in Liverpool, Mr Corbyn won 313,209 votes, compared with Mr Smith's 193,229.
Speaking after the result was declared in Liverpool, Corbyn thanked his rival, Owen Smith, and urged the 'Labour family' to unite after the summer-long contest.
“We have much more in common than that which divides us. Let’s wipe that slate clean from today and get on with the work we’ve got to do as a party together,” he said.
