Joe Beashel

As well as leading the 25-strong London team, which includes seven partners, Mr Beashel will continue to work as a partner in the Financial Institutions Group and to service his existing Ireland- and UK-based clients.

The previous head of the London office, Sharon Daly, has been appointed as a consultant to the firm.

Michael Jackson, managing partner of Matheson, said: “The UK is key to Matheson’s international growth strategy and London is home to most of the world’s largest financial institutions.

“This appointment is further evidence of our commitment to growing our business and to enhancing our offering to our clients in the UK and across Europe.

“As head of the London office, Joe will continue to drive our UK strategy forward and build on the success of the office to date. I and all of the firm wish Joe all the best in his new role.”

He added: “I would also like to thank Sharon Daly for her leadership of the London office for the past five years, a period during which the successful implementation of firm’s strategy for London has seen the office grow and thrive. I look forward to continuing to work with Sharon in her new role as consultant at Matheson.”

Mr Beashel joined Matheson in 2004, having previously been CEO of the Irish subsidiary of a large international financial services company.

He helped to establish the Matheson’s regulatory risk team, originally as part of the asset management department. He advises many leading international and domestic financial institutions on all aspects of regulatory engagement and risk.

His appointment follows the recent arrival of Rory Mullarkey as a partner in the firm’s corporate practice in London.
