Sporborg will replace Nick Claydon, who has led the London office for four years and will now work on integrating the group’s client offer across Europe.
A Brunswick spokesperson said the role would focus on ensuring the group's global offices worked effectively together, reflecting a renewed emphasis on Europe as a region.
Former senior partner at McKinsey Nick Lovegrove will join the firm as managing partner in the US. The role, which has recently been vacant, involves overseeing Brunswick's four US offices.
Sporborg joined Brunswick in 1998 having completed an MBA at Cass Business School and served in the British Army. He has been a partner in the London office for ten years, working in the consumer industries sector and leading Brunswick’s real estate, gaming and lodging practices.
Claydon rejoined Brunswick as a partner in 2001, having been head of communications at British Airways. His clients have included Unilever, Rolls-Royce, Burberry, Thomson Reuters, BP and McKinsey.
Lovegrove will join Brunswick next month after more than 30 years with McKinsey in London and Washington DC. He had spent the past two years at the Albright Stonebridge Group, an international public affairs advisory firm.
