John Lewis names Will Kernan managing director as Peter Ruis departs

The retailer taps a former New Look and River Island executive to take over ahead of the crucial peak trading season.

10 August 2026

John Lewis has confirmed that Will Kernan will succeed Peter Ruis as managing director, taking up the role in mid-September, according to WWD. Kernan arrives with a retail background that includes senior roles at New Look and River Island, two chains that have had to fight hard for relevance in a brutally competitive British high street. Ruis is departing to pursue new projects, ending a tenure in which he pushed John Lewis to sharpen its fashion and homeware credentials and lean further into its department store heritage at a time when many peers have retreated from that format.

The timing of the handover is notable. Kernan takes charge just weeks before the all-important autumn and Christmas trading window, when John Lewis and its Waitrose sibling under the John Lewis Partnership typically generate a disproportionate share of annual profit. A new managing director settling in immediately before peak season is a real test of continuity, and the Partnership will be keen to avoid any disruption to supply chains, staffing or merchandising decisions already locked in for the period.

More broadly, the move continues a period of change atop one of Britain's most storied retail institutions, which has spent recent years restructuring, cutting costs and trying to restore profitability under its mutual ownership model. Kernan's experience turning around value and mid-market fashion retailers suggests the Partnership may want sharper commercial discipline and faster decision-making in merchandising, rather than a change in strategic direction. What subscribers should watch is whether Kernan signals any shift in John Lewis's positioning on price, own-brand development or store footprint once he has had time to assess the business through its most important quarter.
