Squire Patton Boggs global managing partner Stephen Mahon is relocating to London to head up the London office, replacing longtime office managing partner Robert Weekes, who is stepping down from the leadership role but will remain at the firm.

Mahon, who is moving to London from Cincinnati, will retain his position as global managing partner for clients and strategy while assuming Weekes’ responsibilities at the helm of the London office.

Weekes, who has been London managing partner for 10 years, will remain with the firm as a fraud partner in London.

Mahon, who is also a member of Squire Patton Boggs’ executive leadership group, has held other senior management roles at the firm, including global business practice leader and chair of the firm’s private equity practice group.

Squire Patton Boggs chairman and global CEO Mark Ruehlmann commented on the moves, commending both Weekes and Mahon.

“I could not be more grateful to Robert for his leadership of one of our firm’s largest and most important offices,” he said. “Steve is respected among our partners across our 47 offices and as our global managing partner will continue to build on the success the London office has achieved.”

In 2017, Squire Patton Boggs saw its revenue grow 1.7 percent to over $1 million, while profits per partner jumped 1.4 percent to $987,000. The U.S.-based firm has a significant U.K. presence due to its 2011 takeover of Hammonds.

The firm has recently made headlines for its work for under-fire political consultancy Cambridge Analytica, which it is advising on the Information Commissioner’s Office investigation into the company’s use of Facebook data for President Donald Trump’s election campaign.

It is also currently attracting media attention for its links to Trump’s personal lawyer Michael Cohen, whose office in Rockefeller Center was inside the offices of Squire Patton Boggs. Cohen’s office was raided last week by the FBI.

Cohen, who is under investigation by Manhattan federal prosecutors, was given the office as part of an alliance with Squire Patton Boggs formed in April of last year. He was paid a $500,000 annual “strategic alliance fee” by the firm and had an agreement that said he would also receive a percentage of the fees charged by Squire Patton Boggs for clients introduced to it by Cohen under certain circumstances, according to prosecutors.

The firm said last week that it had ended its formal working relationship with Cohen.
