How the UK lost its leading role in the global fight against corruption

The UK last hosted the G7 in 2013 but progress on David Cameron's grand plans has been woeful

The last time the UK chaired a summit of the G7, or the G8 as it was in 2013, David Cameron was in an ebullient mood as he held a closing press conference in glorious late afternoon sunshine by Lough Erne in Northern Ireland. He sensed he had pulled off a diplomatic triumph by putting a new subject at the forefront of world leaders' agenda: the global fight against corruption.

These are really strong commitments that have never been written down in this sort of way and then signed," Cameron said. These are words on a page that the G8 is going to be judged on year after year after year."
