Ocado Retail, the joint venture between Ocado and Marks & Spencer, had an average of 328,000 weekly orders in the fortnight after its September 1 launch. This was down from 345,000 orders a week in the seven weeks prior to the switch, according to internal data seen by The Sunday Times. 

Former partner Waitrose, meanwhile, has seen weekly orders on its website grow to some 190,000 – a near 20% capacity increase in a month.
