He is “pursuing other opportunities”.
Young is reported as saying: “Because of some personal, family reasons, it suits me to leave LDV now. Other factors aside, I would have stayed longer.”
Young, who could not be contacted, quit soon after the Birmingham vanmaker cut production to three days a week in December. It blamed a drop in orders.
His departure was a surprise.
A former Ford executive, Young was part of a new executive team recruited by Russian commercial vehicle maker Gaz in July 2006.
Gaz acquired LDV from Sun, a US private equity group.
Some industry watchers believe Young’s decision is linked to a boardroom reshuffle.
In a statement, Gaz said Young’s replacement as a director of the company was Eugeny Vereschagin, chief financial officer of Gaz power train division.
Martin Leach, executive chairman of LDV, and a former Ford executive, is acting chief executive.
Leach said LDV has been through “enormous change” over the past 18 months, launching new products and making improvements.
