The billionaire Issa brothers are facing personal and professional turmoil. Zuber Issa, a co-owner of Asda, is exploring selling his stake in the supermarket chain, wanting to focus on EG Group. His brother Mohsin is dealing with an extramarital affair and has faced criticism for his lack of experience leading Asda. Zuber seeks at least £500m for his Asda stake, but both Mohsin and TDR would have to agree to any sale. The potential stake sale increases uncertainty at Asda, which has been losing market share to discounters Aldi and Lidl.
