The Real Madrid star, captain of the Portuguese international side and former FIFA World Player of The Year has signed up to become a global ambassador for Save the Children.

Ronaldo has already presented a charity auction in aid of Save the Children's Every One campaign. The campaign seeks to improve child mortality rates across the world and especially help child and newborn survival levels in poor countries reach a par with those of the richer nations.

The star's fundraising charity auction in Egypt benefited from signed shirts from Ronaldo, along with other football icons including Alessandro Del Piero and Lionel Messi.

At its most basic level the Save the Children campaign, launched in 2009, aims to improve child mortality rates globally and draws attention to the inequalities involved when it comes to child mortality. UN figures reveal that tens of thousands of children under the age of five are dying daily.

However, children in poorer countries have a lower chance of survival. The statistics are shocking - nearly eight million children die every year before age five, about one every four seconds - often as a result of hunger or due to preventable illness that can be overcome with simple solutions, generated with a few pounds, euros or dollars...

As well as raising funds to support Save the Children programmes seeking to improve child survival rates, the Every One campaign is also about awareness - hoping to pressure governments to fulfil their promise of achieving the UN's Millennium Development Goal 4 (MDG4) when it comes to child survival. MDGs are development goals supported by the UN's member states and backed by a number of international organisations.

Ronaldo has recently expressed his pride in supporting the children's charity campaign and likewise Save the Children has celebrated the arrival of their star name on the charity team as ambassador.

Save the Children says Ronaldo's charity auction appearance has already helped to raise money that will reach 7,000 children and over 36,000 adults in Egypt, providing access to healthcare and livelihood support - as well as drawing attention to its global Every One campaign to eradicate unacceptable child mortality rates...
