Billionaire businessman Richard White allegedly instructed his lawyer to dump the woman with whom he was having an affair, asking them to write to Sydney wellness entrepreneur Linda Rogan and tell her he had made “alternative arrangements”.

The breakdown of the relationship between the founder of logistics software firm WiseTech Global and Ms Rogan spilled into the open last week after Mr White sued in the Federal Court to recover debts. Ms Rogan alleges that he is wrongly pursuing her for bankruptcy because he is more upset about the failure of the relationship.
