Reed Smith London restructuring partner Charlotte Moller, who is currently acting on the standout mandate of the collapse of Thomas Cook, has quit the firm to join U.S. rival Brown Rudnick.

Moller has been a partner at Reed Smith's London base since 2008, after joining as an associate in 2005 from Norton Rose Fulbright.

She is part of the cross-border Reed Smith team advising the Civil Aviation Authority (CAA) on its efforts to repatriate more than 150,000 British tourists left stranded abroad as a result of the collapse of Thomas Cook. It is the U.K.'s largest peacetime repatriation effort.

Reed Smith is working alongside the CAA's in-house team on issues surrounding the company's insolvency, including: providing advice on licensing and regulatory issues, financing aspects of the group's restructuring, insolvency law and contingency planning for the repatriation of the travellers.

Moller was also part of the Reed Smith team that advised the CAA on licensing and contingency planning when budget airline Monarch collapsed into administration in 2017.

A Reed Smith spokesperson thanked Moller for her contributions to the firm, adding: "We are constantly growing and investing in our key industry groups and continue to enhance our global capabilities. We wish Charlotte all the best for the future."

Her hire represents a relatively rare addition by U.S. firm Brown Rudnick to its London base.

The firm has made a handful of hires in recent years, including corporate partner James Cole from Paul Hastings and special situations partner Iden Asl from Mandel, Katz & Brosnan earlier this year.
