Boss Tim Steiner will be asked about the tie-up when he fields questions on Tuesday. Ocado currently has a tie-up with Waitrose, but it has been suggested that M&S would step into the breach when the existing contract ends next year.
“Interesting rumours recently of secret talks between Ocado and M&S on a number of possibilities, including grocery deliveries and even a suggestion that M&S might buy Ocado’s entire supermarket delivery operation to leave Ocado free to focus on its technology side,” The Share Centre said.
Meanwhile, City analysts tip Ocado to post a fall in full-year earnings, largely linked to an accounting change.
The group is expected to see earnings drop 10 per cent to £75.7 million, but this falls to between £58m and £61m when taking into account new reporting requirements.
