Helen Clark, former New Zealand PM, will step down as UN development chief in April

Helen Clark, the highest ranking woman at the United Nations, is stepping down as director of the UN Development Programme in April, according to an email seen on Wednesday.
The former prime minister of New Zealand told UNDP staff that she had notified UN Secretary General Antonio Guterres of her intention to leave the top post on April 19, at the end of her second four-year term.
“It has been an honour and privilege for me to lead UNDP for eight years,” Clark wrote in the email addressed to “dear colleagues.”
Clark’s departure opens up a race to lead the UN’s largest agency.
Former British foreign secretary David Milliband, who now heads the International Rescue Committee, has been tipped as a possible successor as has French ecology minister Segolene Royal.
Clark, 66, took the helm at UNDP in 2009 and in April last year launched a campaign to run as UN secretary general, which she lost to Guterres.
