Results of the post-mortem examinations into the two horses who died following an incident in the parade ring at Newbury on Saturday have been delayed.

Marching Song, who is part-owned by Graham Thorner, from Letcombe Regis, near Wantage, and Fenix Two were about to be mounted by their jockeys when they fell to the ground and died.

Although the first race went ahead, the rest of the meeting was abandoned on health and safety grounds.

Speculation has been rife since the horrific events that the horses may have suffered from some form of electric shock.

Thorough investigations have been carried out since by all parties concerned, and a section of electricity cable was removed from the paddock area by Southern Electric.

Paul Struthers, head of communications for the British Horseracing Authority, said: “We can confirm that we will not be in a position to announce the results of the post-mortem examinations today.

“Our investigation, which is running in tandem with the investigation being undertaken by Newbury Racecourse and Southern Electric Power Distribution, has a number of other aspects.”

Discussions are also still ongoing as to whether the fixture will be rescheduled.
