Veteran left-wing politician Jeremy Corbyn was elected leader of the Labor Party on Saturday in a landslide vote, casting a spotlight on deep ideological divisions in the once-dominant political organization.
Corbyn, 66, who won nearly 60% of the votes in the four-candidate race, favors Britain's withdrawal from the North Atlantic Treaty Organization, nuclear disarmament and renationalization of the energy sector.
He is also staunchly anti-austerity and has pledged to apologize for the Labor Party's role in launching the 2003 U.S.-led Iraqi invasion.
As Corbyn gave his acceptance speech, shadow health minister Jamie Reed resigned from his post, citing ideological differences over nuclear policies.
