The awards ceremony recognises the achievements of Europe’s top dealmakers and rewards innovative advisory work on some of the region’s most transformative deals over the previous year.

Firms were shortlisted based on their Mergermarket league table ranking, which assesses advisers in each category based on volume and value of deals.

Philip Whitchelo of Intralinks presented the award to Arthur Cox at the prestigious ceremony in London’s Banqueting House.

Brian O’Gorman, managing partner at Arthur Cox, said: “This is the eighth time in nine years that the firm has won this award and is testament to the quality and breadth of work carried out by our corporate and M&A teams who advised on several of the most significant Irish and international deals of 2015.”

The Dublin-based firm said it is the latest in a series of accolades it has won this year.

Earlier this year, the firm won European Legal Team of the Year at the British Legal Awards 2015, was named Ireland Law Firm of the Year 2015 at the IFLR Europe Awards, Ireland Law Firm of the Year by Who’s Who Legal, and Best Firm in Ireland and Best National Firm at the Europe Women in Business Law Awards.
