Supermarket Morrisons is to start its online groceries business by the end of this year after unveiling a tie-up with delivery firm Ocado.
Ocado is closely linked with Waitrose, exclusively delivering the supermarket's products - as well as its own and those of branded ranges - to its customers and the move is likely to spark a backlash.
Mark Price, managing director of Waitrose, recently told The Sunday Telegraph its lawyers would seek to examine any tie-up between the other two companies.
