Primark

Primark began in June 1969 as Penneys, a single shop at 47 Mary Street in Dublin, which still trades today. It was opened by Arthur Ryan with his business partner Micaela Mitchell on behalf of the Weston family, owners of the food group that became Associated British Foods. Ryan's idea was to sell basic, fashionable clothing at the lowest possible prices by buying in volume and keeping costs down, and within a few years Penneys had opened in Cork, Belfast and across Ireland, and in 1973 in Derby, its first store in Britain.

The American retailer JC Penney objected to the use of the Penneys name, and after a 1974 injunction the stores in England were renamed Primark, after an in-house label. A settlement in 1976 confirmed the arrangement still in place: Penneys in the Republic of Ireland, Primark everywhere else.

For three decades the chain grew steadily in Ireland and Britain, but its great expansion came in the 2000s. In 2005 it bought much of the Littlewoods store estate for £409 million, gaining large high-street sites, and in 2006 it opened its first store in continental Europe, in Madrid. Stores followed in the Netherlands, Portugal, Germany, Belgium, Austria, France and Italy, and in 2015 Primark opened in Boston, its first American store. Its Birmingham store, opened in 2019, became its largest. Primark resisted online shopping for years, relying on low prices, huge stores and word of mouth, before introducing an online click-and-collect service in November 2022, prompted by the losses of the Covid lockdowns.

Its low prices have brought intense scrutiny of how its clothes are made. In 2013 the Rana Plaza factory building in Bangladesh, which housed a supplier to Primark and many other brands, collapsed, killing more than 1,100 people; Primark was the largest single contributor to compensation for victims and their families.

Arthur Ryan led the business from its founding until 2009, when Paul Marchant succeeded him; Marchant resigned in 2025 and was succeeded by Eoin Tonge, confirmed as chief executive in March 2026. In April 2026 Associated British Foods announced that Primark would be demerged into a separately listed company, expected by the end of 2027. More than half a century after Mary Street, Penneys remains Ireland's best-known shop and Primark one of Europe's largest clothing retailers.
