Mr Ayre, 43, is a partner in accountancy firm Greaves West & Ayre, of Berwick, which acts for around 400 farming and agricultural estate clients in the North-East and Scottish Borders.

Educated at Fettes College, Edinburgh, and Newcastle Polytechnic, he qualified as a chartered accountant in 1983, and became a partner in the firm five years later. A widower with two sons, Mr Ayre lives in Tweedmouth, where he owns and runs a 45-acre farm.
A keen sailor, he is development officer of Berwick Sailing Club and runs the Charity Diners Club, which has raised pounds 14,000 for worthy causes in the past six years.

He said: "These are times of considerable change for farmers and I am looking forward to helping the group address some key issues facing rural businesses."
