Ms Kelly and Mr Markey will be permanently based in the Dublin office, which will focus on technology, media and telecommunications (TMT), while Mr Cushley and Mr Nagle will divide their attention between London and Dublin.

Darragh Killeen has joined the Dublin office as a senior associate, with two further associates joining this summer. The firm has also appointed Mike Rebeiro, formerly of Macfarlanes and Norton Rose, as TMT and digital transformation consultant.

In a joint statement, Ms Kelly and Mr Markey said: “Our links to Browne Jacobson go back several years. It has been a very positive long-term working relationship on both sides and there are strong cultural and practice synergies which we are confident will help to make the Dublin office a great success.

“The firm’s achievements in social mobility and inclusion are simply outstanding and something which we are excited and proud to be a part of and to bring to the Irish market. The initial focus of the Dublin office will be on non-contentious and contentious IP, technology, data privacy and digital transformation.

“We will be leading a strong team in Ireland integrated into a 40-plus lawyer team focused exclusively on this space across London and Dublin. This will bring a greatly enhanced offering to clients both international and domestic with increased international reach, EU 27 access and US links.

“Clients are increasingly transacting business and resolving disputes through Irish law. We believe that there is enormous opportunity to grow the Browne Jacobson Dublin office aligned with strengths of the Irish economy in particular in technology, life sciences and data privacy and we are very excited to lead this.”

Mr Cushley added: “Anthony and I originally hail from Derry and Kerry and have been keen to do this for some time. We are delighted to be part of the firm’s first overseas office and indeed to have the opportunity to work as founding partners with Jeanne & Ciarán.”

Richard Medd, managing partner at Browne Jacobson, said: “Legal services are becoming more international, and many of our clients who are doing business in and through Ireland expect seamless cross-border services.

“We are committed to establishing a strong presence in Ireland and the opening of an office in Dublin with leading Irish based experts is therefore an exciting and logical next step for the firm.”
