Andrew Diamond, currently a partner and the firm’s head of residential property, will take up the role on 1 October.

He will succeed Alasdair Cummings, who is stepping aside after 14 years in the role – a period during which Lindsays has completed six mergers and seen annual turnover grow from £9 million to almost £28m.

A handover process is already underway, following which Mr Cummings will remain a partner.

Mr Diamond, who joined Lindsays through its merger with MacLachlan and MacKenzie in 2012, aims for the firm to continue its growth organically, as well as through mergers and strong strategic hires.

He said: “I am delighted to be taking on this role. I am very much the continuity candidate. And, while in politics that may not always be viewed favourably, it is a good thing for Lindsays. It’s business as usual here.

“We are clear in our identity as an independent Scottish firm, working with Scottish families and businesses. There will be no change to that. We will continue with steady, strategic growth on the same path as we have followed.

“Our culture at Lindsays is our greatest asset. Our people matter. We have the soul of a smaller firm but with all the benefits of scale. That is down to Alasdair’s leadership, for which we are all grateful. I have very large shoes to fill.”

Mr Cummings’ Lindsays story has seen him rise from trainee to managing partner, beginning in 1986, with only a five-year gap during which he worked for a London legal firm before returning to Lindsays in Edinburgh in 1993 to help grow its corporate and commercial law services.

He said: “Lindsays means so much to me. To be Managing Partner of this firm, with its tremendous team, has been the undoubted highlight of my career.

“The past 14 years have been a successful and exciting journey. Together, we have achieved good growth, a wider geographic footprint and become a full-service firm, of which I am incredibly proud. The time, however, feels right for a new voice to lead Lindsays into the next stage of that journey.

“My current three-year term as managing partner was due to end next March and I was always clear that I would not be seeking another. With that in mind, making a change now feels like sensible succession planning. Andrew is a very worthy successor and I look forward to supporting him in any way I can.”

Nina Taylor, Lindsays’ chair, said: “Alasdair has led Lindsays with purpose, professionalism and integrity. His leadership typifies our firm’s people-first approach to everything. Our thanks go to him for the success he has delivered for the firm and our very best wishes go to Andrew as the baton is passed on. The partnership is right behind him.”
