Lantra chief executive Peter Martin is leaving the organisation after 12 years to "take up an international career."
Martin is credited with securing re-accreditation of Lantra as a Sector Skills Council, and developing new strategic and business plans for the organisation.
Deputy chief executive Robert Tabor will take over as acting chief executive while Lantra reviews its operations. It plans to restructure the organisation around three main areas: Lantra Awards, online skills and projects.
Chair of the trustees Valerie Owen said: "It has been a privilege to work with Peter, who has championed key skills policy issues for the land-based sector and ensured Lantra’s work has been truly employer owned and led. The trustees wish Peter every success in the future."
Martin said: "Agriculture and the wider land-based industries have an exciting future, and I am sure that Lantra will share in their success."
In a statement the organisation said of the future: "We will focus on supporting agricultural and other land-based businesses to increase their profitability by raising the skills levels of their workforce. As a result, our work will also support wider economic development."
