Tesco and Booker have increased their estates this year, while The Co-op and Spar were among those reducing numbers. Beth Phillips reports

There’s been a rash of swap shopping among retailers in the past year, changing the landscape of UK grocery.

Those joining in included Asda buying Netto, indies snapping up former Somerfi elds from The Co-operative Group and Tesco’s convenience chain One Stop buying indie retailer Mills Group.

One Stop’s activity helped parent company Tesco add 167 stores to its estate in the past year, taking its burgeoning store portfolio to 2,682 stores.

When you include its 471 forecourts attached to its supermarkets, it takes its estate to 3,153 stores – the biggest UK grocer by store numbers.
