David Beckham has launched a global fundraising campaign with Unicef to support vulnerable girls across the world.

The former footballer and father-of-four announced the campaign on Tuesday (April 15) as part of a month-long series of events leading up to his 50th birthday on May 2.

Long-time Unicef Goodwill Ambassador David said in a statement online: "We are witnessing a global funding crisis where the most vulnerable children are suffering the most and urgently need our help."
