John Lewis & Partners is a brand of high-end department stores operating throughout Great Britain, with concessions also located in the Republic of Ireland and Australia. The brand sells general merchandise as part of the employee-owned mutual organisation known as the John Lewis Partnership, the largest co-operative in the United Kingdom. It was created by Spedan Lewis, son of the founder, John Lewis, in 1929. The chain has promised since 1925 that it is "never knowingly undersold" â it will always at least match a lower price offered by a national high street competitor.
