Prime Minister Joseph Muscat, an avid Milan supporter, met former Brazilian and Milan footballer Kaka and a number of entertainers when he took part in the Global Citizen Festival in New York's Central Park, conveying a message on the need for global action against extreme poverty and related polio.
Thousands of people attended the event, held to coincide with the presence of many world leaders for the UN General Assembly.
The line-up of participants included politicians, industry leaders such as Bill Gates and Ed Sheeran, entertainers and singers such as Beyonce, Coldplay and Ed Sheeran as well as Brazilian footballer Kaka.
Dr Muscat said the world was at the verge of eliminating polio. The Commonwealth leaders meeting in Malta next month would seek to commit to the elimination of polio, for the second time in the history of the world.
