After buying a petrol station on Brandlesholme Road in Bury, just over 20 years ago, they built a sprawling business empire worth billions.
But since snapping up Asda for £6.8bn in February 2021, billionaire brothers Zuber and Mohsin Issahave come under greater scrutiny.
Here we take a look back at what's been a busy and at times dramatic year for the Blackburn-born entrepreneurs - which has seen them strike some massive deals, and face questions from politicians.
The brothers, who according to the Sunday Times 2023 Rich List have a combined fortune of £5bn, recently sought to reassure MPs over the structure of their company and its tax and debt position. "We would like to take this opportunity to confirm that no companies in the Asda ownership structure are incorporated in jurisdictions outside of England and Wales due to any 'tax haven' status,'" Mohsin Issa wrote to MP Liam Byrne, chair of the business and trade committee.

Meanwhile, earlier in 2023, executives from the Issa brothers' owned Asda - and the UK's other big four supermarkets Tesco, Sainsbury's and Morrisons - denied they were profiteering from customers who have witnessed soaring increases in their food bills during the cost-of-living crisis.
