U2 have made their first UK festival appearance since the early 1980s, headlining Glastonbury.

The Irish stars ignored a demonstration by protest group Art Uncut, who inflated a 20ft balloon emblazoned with the words "U Pay Your Tax 2".

Minor scuffles broke out as the balloon was removed by security men.
