J Sainsbury, the embattled UK food retailer, has decided to go head to head with its shareholders over the £2.4m (€3.6m) controversial bonus payment to outgoing chairman Sir Peter Davis.

The supermarket chain, facing rebellion from the UK's two largest shareholder groups, has now decided to include Sir Peter's bonus details within the company's remuneration report, due to be voted on by shareholders at the annual meeting next Monday.
