Morrisons restructuring 'had to be done'

The restructuring of Morrisons "had to be done" as internet shopping and discounters are stopping the growth of the "big four" supermarkets, retail expert Rahul Sharma has said.

He told Radio 4's Today programme that these supermarkets were "losing even middle class shoppers" to the discounters - and the customers were then expensive to "win back".
