Arnold & Porter has launched its first City banking regulatory practice with the  hire of a Katten Muchin Rosenman financial services partner in the London office. 

Tim Aron is set to join from the US firm, where he represents a wide range of clients within the financial sector including banks, fund managers and insurers. He previously worked at the Financial Services Authority (FSA), the forerunner to City watchdog the Financial Conduct Authority (FCA).

Arnold & Porter's London office chief Tim Frazer said: "Tim's service at the FSA brings to the table the kind of practical experience that will hugely benefit our clients in the UK."
