At lunchtime [on the 28th October], activists entered the grand hall of the Natural History Museum and surprised security guards by staging a melodic protest at the entrance to the shell-sponsored exhibition.

Starting with humming and building up to a rousing chorus it took guards a little while to work out what was happening. meanwhile leaflets were handed out to the bemused public. as shell-hired security forcefully marched singers out of the building, more voices kept emerging, and it took several minutes to eventually clear the hall by which time a lot of leaflets had been handed out and the point had been made.

Outside the museum, more than 500 leaflets were handed to people attending the exhibition, and banners and posters showed the real work of Shell, rekindling the memory of Ken Saro-Wiwa and the Nigerian activists working to stop shell’s blight of the the land and the environment in the Nigerian delta.

Public response was very favourable – the irony not lost on most people.

One guard let slip that the security operation is costing shell £2000 per day to protect the exhibition from likely protest.
