Tributes have been paid following the death of the first woman to serve as a United Nations Under-Secretary-General; the third highest rank in the global organization.

Dame Margaret Anstee, who was from the United Kingdom, joined the UN in 1952 and was appointed as a so-called USG in 1987.

She was also the first woman to head a military peacekeeping operation, in Angola, in the early 1990s.

Daniel Johnson spoke to Dame Margaret in June this year, shortly after she celebrated her 90th birthday.
