Skadden Arps Slate Meagher & Flom white collar crime partner Elizabeth Roberston has picked up a role on the board of social mobility network PRIME.

PRIME is an alliance of law firms from across the U.K. with a commitment to offering work experience to those from a socio-economically disadvantaged background.

State school and polytechnic-educated Robertson, who is based in the firm's London office, is one of two new board members for PRIME. She joins alongside Lucy Lewis, the head of employment boutique Lewis Silkin's Cardiff office. Both join the board this month.

Robertson said in a statement: "I've long been committed to diversity issues, including the need for lawyers to represent all walks of life. I'm pleased to take on this role to more fully participate in ensuring greater inclusion in our profession."

Freshfields Bruckhaus Deringer real estate partner Annette Byron stood down from PRIME's board last year when her term expired, while Binda Patel, head of innovation at social mobility organisation The Sutton Trust, also left the board earlier this week.

In October, a Legal Week investigation found that nearly half of the Magic Circle's partners were Oxbridge-educated.

Commenting on the findings, Dr Wanda Wyporska, executive director at Equality Trust, said: "Sadly, despite decades of talk about opening up access, social mobility and widening participation, the truth holds that unless you have attended a fee-paying school, you are unlikely to reach the dizzy heights of the Magic Circle."

Elsewhere, Baker McKenzie and Linklaters were recognised as industry leaders in social mobility, according to a City of London Corporation-backed ranking of the U.K.'s top employers.
