King & Wood Mallesons SJ Berwin and TLT have both won first time places on Sainsbury's legal panel after the supermarket chain carried out a review of its advisers.

Sainsbury's – which holds a review every three years – has also held on to key advisors including magic circle firm Linklaters, CMS Cameron McKenna, Addleshaw Goddard, Dentons and DWF, while newly merged firm Wragge Lawrence Graham has also retained its spot.

Charles Russell and legacy media boutique Simkins are the only firms not to have been re-appointed to the panel however Sainsbury's will continue to work with Charles Russell on a bespoke basis.

The review, which was run by Clare Russell and Paul Jenkinson from the Sainsbury's in-house team, together with Phil Sykes from the Sainsbury's procurement team, focused on continued cost management. Firms were asked to demonstrate value for money and a willingness to work collaboratively with in-house teams to deliver legal services to the business.

Sainsbury's head of legal Nick Grant, said: "We take this opportunity every three years to look at the quality and range of firms in the Sainsbury's legal community to ensure the company continues to receive the best possible service.

"I'm very pleased with the outcome – we've managed to both bring in new talent and retain the expertise and experience of long-standing Sainsbury's firms. I and my in-house team look forward to working with them all over the next few years to deliver the first rate legal service that our business has come to expect."

The last review in 2011 saw the panel divided into 12 sub-panels, including a quartet of firms advising on property, as well as three firms handling employment matters.
