John Hargreaves and family
Liverpool-born Hargreaves, 73, built the Knowsley-based Matalan discount chain. He floated it in 1998, when it was valued at £200m, but bought it back again in 2006 for £817m. In 2010 Hargreaves refinanced the company in a £525m deal that saw him take a £250m dividend. After a tough 2015, Matalan's profitability improved last year with full-price sales rising 29.1% in the final five weeks of 2016. The heavily indebted company last year placed itself in Lloyds Banking Group’s “special measures” unit. We value Matalan at £200m and add £300m for other family assets.
