New York City's public advocate Bill de Blasio has won a Democratic mayoral primary, unofficial results show.
With some 97% of precincts reporting, Mr de Blasio secured some 40% of the vote, but may still face a run-off with former city controller Bill Thompson.
In the Republican race, Joe Lhota, the former head of NYC's transit service, won with about 52%.
The winner of each party's primary will vie in November's mayoral election to replace incumbent Michael Bloomberg.
