I'm humbled to work for UN, says Victoria
Victoria Beckham has told the UN that she was "very humbled" and "honoured" to act as a goodwill ambassador for the organisation's Aids campaign.
"This is the beginning of an incredible journey for me," she said.
The former Spice Girl said she had been inspired by talking to women in Cape Town.
"I came home and knew I had to do something," she said. "It's taken me getting to 40 years old to realise I have a responsibility as a woman, as a mother. I have a voice people will listen to.
"Every woman out there has the right to health and the right to give her children a healthy future," she said.
"Children, babies, should not be born with HIV, and we can stop that - we are very, very close to stopping that - which is why I'm sitting here now. We can't give up, we have to keep going. I feel very humbled, I feel honoured. Thank you for mentoring me through this. This is just the beginning for me."
