Mr Freeth's name appears on the British government's diplomatic service and overseas list for his services to the farming community. He is one of 44 people worldwide who will be invited to Buckingham Palace to receive his MBE from the Queen.
Mr Freeth and Mr Campbell took their case to the Sadc Tribunal in 2007 in a bid to save their farm, which was the biggest producer of export mangoes in Africa. They were later joined in their application by 70 other farmers. Despite winning their case, most have now been evicted from their farms.
Speaking by phone from Harare yesterday, Mr Freeth said he was "blown away" by the honour conferred on him. "I had no idea that my name had been put forward."
The British honours system is one of the oldest in the world and evolved over 650 years as the country sought to find ways to recognise merit and service.
Mr Freeth and his family lost everything they owned when their houses and their linen factory were burnt down last year.
He believed he would be able to return and rebuild his farm, "but not as long as we have a dictator ruling the country".
"(Robert) Mugabe is responsible for appointing the judiciary and the attorney-general as well as the police commissioner, Augustine Chihuri, who does not do his job and see that court orders are enforced," he said.
Mr Freeth said that as soon as the World Cup in SA was over, there would be a rise in violence in Zimbabwe.
