The second, decisive round of elections was held on Sunday, after a first round in which eleven candidates ran.
The socialist Seguro, a center-left politician who advocates social democratic policies, received between 67 and 73 percent of the vote, according to two exit polls. The 63-year-old Seguro is seen as a guarantor against a right-wing drift in Portugal.
Opponent Ventura, 43, and his far-right party Chega received between 27 and 33 percent in the polls.
Around eleven million residents were eligible to vote. The president has limited powers but has some veto power and can dissolve parliament.
