Great Tew Horse Trials will not run in 2013 following a change of policy on the Oxfordshire estate where it is held.
The decision was made by Nicholas Johnston, the owner of the Great Tew Estate, and event organizer Charles Etherington-Smith, after eight successful years of the affiliated event.
The 2012 event (9-10 June) was cancelled due to the wet weather.
Mr Johnston said: “We have really enjoyed hosting the Great Tew Horse Trials over the past eight years.
“It has become a very popular couple of days both within the eventing calendar and for us all on the estate itself and we hope that there may be another chance to participate in the eventing season in the future.”
Mr Etherington-Smith added: “It has been great fun running the event on this lovely estate and perhaps at some stage in the future there might be an opportunity to resurrect it.
“Nicholas and his family are great supporters of the sport and are sorry to see the event go.”
British Eventing said it would look for alternative events to run in this calendar slot.
