The upmarket grocer’s long-standing deal with Ocado will come to an end in August, after the online retailer-cum-tech provider penned a joint venture deal with M&S.

The technology behind Waitrose’s online platform is currently provided and maintained by Ocado, while the supermarket chain also sells a selection of its own-label products on Ocado.com.

In a bid to maintain its online customers buying Waitrose products through those two channels, the grocer is working on 5,000 new or reformulated products, according to The Guardian.
