Ocado chief executive Tim Steiner and Marks & Spencer’s chair Archie Norman and chief executive Steve Rowe have all been named in court papers that unveil a bitter feud over online grocery shopping according to The Times. 

The case is centred around Jonathan Faiman, co-founder of Ocado who exited in 2010 and went onto set up a new grocery delivery venture -Today Development Partners (TDP).

Following the announcement in February that Ocado had signed a deal with M&S to launch its online food service, TDP revealed in May it had struck a deal to be Ocado’s replacement at Waitrose.
