Ex-police captain Eric Adams takes early lead in New York mayoral primary

• Centrist Democrat claims most first-choice ballots
• Ranked-choice voting means primary winner due on 12 July

Brooklyn's borough president, Eric Adams, appeared to take a fragile lead in New York's Democratic mayoral primary on Tuesday, but it could be weeks before it becomes clear who is on top in the first citywide election to use ranked choice voting.

As ballot counting began, more Democrats ranked Adams as their first choice in the race than any other candidate.
