Sales at upscale regional supermarket operator Booths climbed 7.6 per cent in the four-week period to January 5.

Like-for-likes were up 3.7 per cent as the retailer benefited from the wave of middle-class consumers that has also given rival Waitrose a successful Christmas.

Booths chairman Edwin Booth said: “Despite a tightening economy, Booths achieved good product availability with increased customer interest in high-quality local food and drink.”

Booths plans to open three stores over the next two years.
