Swinging round the side of the Palais, we arrive at the Pregny Gate where long queues of attendees are slowly navigating the UN’s complex security process. By the time I have been given a name badge and my bags have been scanned, the opening plenary of the Forum is about to start. I rush across the Palais’ grounds, into a large atrium where security guards initially bar entry into Room XX. It’s full I am told. I manage to find another entrance and make it inside. Looking round the vast hall as I enter, coloured stalactites on the ceiling add to the cavernous feeling of the place.
