Proceeds from the shirts, which are available for £90 on Beckham’s website, will go to Born Free Africa, which prevents the spread of the disease from mothers to children.

Beckham, who is a UN ambassador, told Harper’s Bazaar: “For the last few years I have designed an exclusive World Aids Day T-shirt to raise money and awareness on this important day.

“This year, for the first time (and along with a little help from Harper) I've created an adults T-shirt with a matching mini-version for children too. All profits from the sale of these T–shirts will go to Born Free Africa who are doing such wonderful work on the ground.”
