A charity fundraising event being undertaken by a Norfolk business has been left in jeopardy after their designated driver unexpectedly withdrew from the attempt.

Quantity surveyors from Andrew Morton Associates, which is based in Oulton, near Aylsham, are planning to raise over �1,000 for local charities by walking Ben Nevis, Scafell Pike and Snowdon in under 24 hours, leaving on May 20.

Director Andrew Morton is one of those taking part in the challenge raising money for a village in Kenya and Aylsham Recreation Ground, alongside James Cleaver who is fundraising for PACT Animal Sanctuary and Simon McCann who is doing the challenge to raise money for SMILE Train, an international charity that provides cleft palate surgery to those in need in developing countries as well as providing training to doctors. Another person who wishes to remain anonymous is also taking part.

Mr Morton said: 'We'll be walking for 16 hours and driving in between mountains. If we don't have someone else to help out with the driving we will have to cancel because it's just too dangerous to drive when tired. I'm absolutely gutted.'

AMA is appealing for someone to step in at short notice to help with the driving. The person must be over 25 and free from Friday, May 20 to Monday May 23 inclusive. Mr Morton's contact details are available on his website www.ama-qs.co.uk
