This paves the way for the two businesses to work closer together as they seek growth across the UK and internationally.

The investment sees Irwin Mitchell partners Bruce Macmillan, Craig Marshall and Mark Higgins join the newly formed Wright, Johnston & Mackenzie management board as the two firms seek to share best practice and take advantage of opportunities to further grow their businesses.

Wright, Johnston & Mackenzie will continue to operate under that brand in Scotland for the immediate future with managing partner Fraser Gillies heading up operations.

Mark Higgins, managing partner for Irwin Mitchell in Scotland, said: “Over recent weeks and months, teams and colleagues from Irwin Mitchell and Wright, Johnston & Mackenzie have been meeting and supporting each other with a focus on the future.

“Now that the deal is complete, we can accelerate our plans to grow our businesses and we’re looking forward to working together to maximise the opportunities both sides of the border for our clients.”

Mr Gillies added: “Both law firms have a similar, collaborative culture, with clients at the heart of everything we do, and it’s been impressive to see the ideas and opportunities our colleagues have shared since the deal was announced back in September last year.

“We now begin the next chapter in our history, and we’re excited about what we can achieve together.”
