New Zealand Prime Minister Jacinda Ardern went to see the Queen lying in state after becoming one of the first foreign leaders to arrive in the UK for the funeral.
Television footage showed Ms Ardern stopping to curtsy as she filed past the coffin at Westminster Hall on Friday.
She will be one of the 500 world leaders and dignitaries who will be attending a Buckingham Palace reception that is being hosted by King Charles on Sunday ahead of the Queen's funeral the following day.
