Sir Sir Ranulph Fiennes and Natalie Pinkham have been appointed ambassadors for Seeing Is Believing, an initiative launched by Standard Chartered Bank, the International Agency for Blindness (IAPB) in 2003.

The charitable organisation is the official beneficiary of this year’s Standard Chartered Great City Race (July 12), and Pinkham joins celebrities including Oliver Mellor running the 5km race blindfolded, with Fiennes taking on the role of race ambassador alongside visually impaired Team GB 2012 Paralympic hopeful Jack Roughan, and five-time Paralympic gold medallist Noel Thatcher.
