RPC has been appointed as the primary commercial contracts legal adviser to UK developer and designer shopping outlet owner McArthurGlen.

The top 50 firm saw off competition from a number of competitors to land the open-ended agreement, which will see it negotiate of a wide range of third party supplier contracts, including IT and web based services. The role also includes the management of McArthurGlen's contracts portfolio.

After first setting up in 1993, McArthurGlen's current portfolio of designer outlets has grown to 21 centres across eight countries in Europe.

The RPC tendering team was led by commercial, IP and technology partner Oliver Bray.

Bray said: "We enjoyed the whole pitch process, not least because the McArthurGlen team were so clear in what they needed, both from a business and a legal perspective – we're all thoroughly looking forward to working with them."

McArthurGlen's head of legal Giles Millerchip said: "Our business continues to expand rapidly and we strive to deliver excellence in all we do. RPC will help us streamline our commercial contract work to deliver an even more efficient and sophisticated service to an ever higher standard."

The news comes after McArthurGlen hired former Nabarro senior partner Simon Johnston as its deputy chairman in April.

McArthurGlen was a longstanding client of Nabarro and Johnston, who advised on its set-up in 1993 ahead of the launch of the company's first outlet, Cheshire Oaks, in 1995. Johnston was Nabarro's senior partner from 2001 to 2012 before standing down to be replaced by Graham Stedman.
