Waitrose only major supermarket with majority Tory

Shoppers at Tesco, Sainsbury’s, Morrisons, Lidl and Aldi have all swung to Labour from Conservative since 2019

The election may not yet be in the bag for Labour, but research suggests it is in the shopping basket.

The party’s voters now make up the majority of customers at all leading supermarkets apart from Waitrose, according to the latest polling from retail research firm GlobalData.
