A Devon farmer and former NFU county chairman has admitted allowing land on his farm to be used to grow cannabis.
But John Shears, 70, of Lower Nattadon Farm, Chagford, Devon, denied a second charge of producing the drug on his farm in Dartmoor.
He now faces a trial at Exeter Crown Court in the new year.
A second man, Daniel Perryman, 26, of Exeter Road, Kingsteignton, Devon, admitted producing cannabis and he will be sentenced after Mr Shears’ trial.
Devon and Cornwall Police discovered 189 cannabis plants when they raided Mr Shears’ farm in May.
Officers seized the cannabis plants along with suspected drugs production equipment from the farm.
Mr Shears began his career working horses for Dartington Woodland and then progressed to lorry driving. He has farmed, run a cattle transport business and trained racehorses.
He was an active member of the NFU and served as chairman and vice-chairman.
