Upmarket grocer Waitrose has signed a deal with Unimarc supermarkets which will see the chain supply food and drink products to Chile, it has been reported.

Offering over 40 lines to more than 100 shops in Unimarc stores, Waitrose is to sell a variety of traditional British favourites as well as penne pasta and stuffed olives as it seeks to extend its international reach.

Such a partnership comes at a time of considerable upheaval at Waitrose, according to The Guardian, as its long-term partner Ocado announced a new deal with rival Morrisons earlier this month, causing relations to become strained as rumours abound that Waitrose may be looking for new opportunities.

Waitrose has a presence in 46 countries worldwide and is continuing its expansion plan both domestically and abroad after international sales jumped 20 per cent in the year to January 26th 2013.

Commenting on the latest export deal, David Morton, Waitrose‘s Business-to-Business Director told the newspaper: “South America, in particular Chile, has a growing economy and we were approached by Unimarc to help meet the demand for more cosmopolitan flavours among their customers.

“Wherever we sell our products overseas we find the bestsellers are food and drink associated with Britain, such as tea and biscuits.”
