The U2 frontman has been a keen anti-poverty campaigner for years, with a particular focus on Africa, lobbying governments to give aid to impoverished countries to fight disease and help the world's poor.

Earlier this year (Oct15), he told a United Nations conference on aid that commerce is key to ending world poverty, and now he has appointed former U.K. International Development Secretary Douglas Alexander to advise him on how business can increase the wealth of poorer nations.

According to Britain's Financial Times newspaper, Alexander will advise Bono on, "initiatives aimed at catalysing greater investment within and beyond Africa to drive economic growth, together with technology investment".

The singer and activist insists the former Labour Party Member of Parliament, who suffered a shock defeat at the 2015 U.K. general election, will be able to help him with his development projects.

"Music is what I do and it's given me the opportunity to do a lot of other things besides, where Douglas Alexander's experience will be of great value," he tells British newspaper The Guardian.

"I've been lucky to work with a lot of bright, committed people in my activism, and he will be a great new partner for all of us. We come from different arenas, but we share a commitment to tackling poverty through sustainable development, and a belief that both governments and businesses have an essential role."
