Currently head of property at the Crown Estate in Scotland, Mr Laidlaw will take over responsibility for the RHASS, aiming to strengthen the society’s influence in promoting and protecting the interests of land based industries on behalf of its 15,000 members.
He will also oversee the £20 million investment in the 113-hectare (280-acre) Royal Highland Centre site at Ingliston which attracts more than one million visitors each year.
Mr Laidlaw said: "As a lifetime RHASS member and regular show-goer, I am deeply honoured and excited at the prospect of playing a pivotal role in the Society’s future.
"Attending the Show this year will be of even greater significance and it will be an ideal opportunity for me to look at the Show with fresh eyes before I take the reigns officially at the end of the summer."
Mr Laidlaw is a family man with a keen interest in the outdoors, rugby and the countryside.
