Waitrose is contracted to supply Ocado with produce until 2020, with a break clause in 2017.
But Waitrose managing director Mark Price has raised concerns that Ocado’s ongoing talks to help Morrisons set up its own online outlet could breach their existing deal.
Price told the Telegraph that he would “never knowingly sign a contract with Ocado that agreed to them working with another retail competitor”.
“We have moved to defcon one [on online expansion] because we don’t know where this is going to end up and we are now working on adding considerable extra capacity to Waitrose.com,” he added.
Ocado said at last week’s shareholder meeting that it was continuing discussions with Morrisons about an online deal, but that any arrangement “would be complementary to Ocado’s existing partnership with Waitrose, which would be unaffected by any potential agreement with Morrison”.
Ocado’s shares spiked in March when it confirmed discussions with Morrisons that centred around its online know-how, as Morrisons tries to make a long-awaited push into internet shopping.
Meanwhile, almost a quarter of the firm’s shareholders voted against its remuneration report at Friday’s AGM.
More than 13 per cent voted against the firm’s long-term incentive plan, after the firm declined to give details on the targets that staff needed to hit to earn these payouts.
