The 41-year-old launched 7: The David Beckham UNICEF Fund last year and has shared all about his "inspiring time" when he travelled to Swaziland, Africa, to see the effect of his charity work on children living with HIV/AIDS in the impoverished country.

The former England soccer captain took to social media to share an image of his visit, which he captioned: "Had an inspiring time in Swaziland with @unicef to see how my 7 Fund is supporting children living with HIV #7Fund #Beckham#DavidBeckham #UNICEF (sic)."

"It makes me very proud that the money that the 7 Fund provide has helped these amazing mothers to give birth to perfectly healthy HIV negative baby's ... @unicef (sic)."

And David - who has been a long-standing Goodwill Ambassador - shared a video of children in the village dancing.

He captioned the clip: "Sometimes there are days and people that inspire you and make you feel proud that you have made a difference through the work we do on 7 Fund ... this was one of those moments....@unicef (sic)"

And the father of four - who has sons Brooklyn, 17, Romeo, 13, Cruz, 11, and four-year-old daughter Harper with his wife Victoria Beckham - has revealed the Beckham brood are also proud of him and the success of his campaign.

Speaking to People about his family's support, he said: "They understand and respect it. I'm proud to tell them what I'm doing, and I think it makes them proud as well."
