Robert Sinclair, chief executive of AMI, said: "The dinner, which will be held at 8 Northumberland, London, will be addressed by Rory Mackenzie who many remember for his inspiring rendition during the London 2012 Paralympic Games closing ceremony at the Olympic Stadium. "AMI and Abbey for Intermediaries, sponsers of the event, are delighted to arrange for our guests to hear from a former combat medical technician who was badly injured in Iraq but has since rowed the Atlantic, learned to ski and raised considerable sums for charity.”
