Full coverage: Jeff Leo

Wealthy American investor Mary Wenning is claiming in the High Court that “very large sums of money” she believed her company was investing in Ireland have gone missing. This is denied by Jeff Leo, who will now be questioned in court on the matter.

An adviser to US businessman Jeff Leo allegedly warned a figure close to wealthy chicken farmer Mary Wenning that he would report her financial affairs to the IRS. "If this drags on... I fear he will play informer on her."

Wealthy Ohio chicken farmers Mary and James Wenning say they invested funds with Jeff Leo and trusted him when he told them to transfer their share interests. Now they claim he usurped their voting rights, leaving them millions out of pocket.

Wenning Holdings was put into voluntary liquidation in 2023 by Leo, an American businessman and former director of bust AI firm Altada. A liquidator, appointed by shareholders, is now investigating an alleged asset transfer shortly before it was wound up.

In terms of value, the insolvent Cork artificial intelligence firm was described as a "melting ice cube"; without a quick sale staff will leave and there will be nothing left. But a liquidation report has raised "weighty" concerns about the company's borrowings and spending.
