Greenpeace will target Waitrose in the run-up to Christmas in protest against its partnership with Shell.

The environmental campaign group said it would target dozens of Waitrose stores in the coming weeks.

It has also released a spoof version of Waitrose’s TV Christmas advert, starring celebrity chefs Delia Smith and Heston Blumenthal.

The group said Waitrose’s partnership with Shell, which it described as “an environmental villain” for its oil drilling in the Artic, undermined the supermarket’s green image.

“Waitrose trades on its caring, green image. It’s going to lose that carefully nurtured look very soon, unless they drop Shell,” said Greenpeace campaigner Sara Ayech.

Waitrose is in the process of converting all its petrol stations to Shell over the coming weeks. The supermarket said it would be rebranding its 13 forecourts to Shell by Christmas.

A spokeswoman for Waitrose said: “We put as much thought and careful consideration into our relationships with other businesses as into everything we do. In the context of Shell worldwide, the arrangement we have with them is small.

“The scale of our involvement with Shell amounts simply to their operating the 13 existing petrol stations next to our branches and our selling Waitrose products in two Shell forecourts.

“Environmental issues are of great importance to Waitrose and Shell has assured us that they will meet US legislation and international conventions, operating with respect for the environment and for the people who live in the Arctic and sub-Arctic regions.”
