On Sunday, 30 young leaders from six cities around the world met at the City Football Academy ahead of the inaugural Cityzens Giving Young Leaders Summit.
The week-long event is designed to help the young leaders develop their skills and learn from each other through a variety of workshops and activities.
Day One included introductions, ball skills and blindfold football – and tennis ace Marion Bartoli dropped in. Click through our gallery of the action-packed day!
