Almost half of U.K. lawyers say they are unprepared to deal with the impact of Brexit, according to new research that also sheds light on the extent to which large law firms are expecting to move jobs outside of the U.K. as a result of its split from the European Union.

The Thomson Reuters report, “Helping to Understand the Impact of Brexit,” draws on a survey of more than 250 legal service professionals, including interviews with lawyers at Allen & Overy, Baker McKenzie, Gibson, Dunn & Crutcher, Pinsent Masons, and HFW.
