The ex-Bradford City chairman will work as an advisor and has defended his record in the wake of some criticism from Leeds fans and press alike.
"I made the mistakes, and I didn't try and hide them, deny them or blame somebody else which many people do," said Richmond. "You can call me whatever you want, but never call me dishonest. I made a mistake, held my hand up and admitted it.
"The experiences of the final chapter at Bradford have left me a better, stronger person and I will not make those mistakes again. Although the end at Bradford left me broken-hearted, my heart is being mended again with my involvement in Leeds."
Confirming his role with the consortium, Richmond said: "I have assisted in putting the plan, the strategy, the budgets together to those items which are football related.''
