The new head of the World Health Organisation (WHO) is rethinking a plan to appoint Zimbabwe's President Robert Mugabe as a goodwill ambassador.

Meanwhile, the UK government described his selection as "surprising and disappointing" given his country's rights record, and warned it could overshadow the WHO's work.
