The trial of Tom Henderson, the founder and former chief executive of the disaster relief charity ShelterBox, begins at the Old Bailey in London today.
Henderson, 64, of Helston, Cornwall, denied charges of attempted theft and conspiracy to defraud the charity at an earlier hearing at the Central Criminal Court in March.
In a trial that is expected to last 10 weeks, Henderson will appear alongside his 35-year-old son. John Henderson, of Hayle, Cornwall, has pleaded not guilty to charges of conspiracy to commit fraud by abuse of position and possession of a firearm.
A third defendant, Darren Gervis, 42, of Mosterton, near Beaminster in Dorset, is accused of assisting the Hendersons to hide the fraud by setting up a company. He has also denied a charge of conspiracy to commit fraud.
Tom Henderson was dismissed from ShelterBox – which provides emergency shelters and supplies to areas hit by disasters – in 2012.
