Sheffield GM John Gilburn has defended the right of Nottingham boss Rachel Corden to bar runners owned by GTA secretary Dave Houfton from trialling or racing at her track.

Gilburn said: “I don’t know the circumstances at Nottingham, but I would absolutely defend the principle of a management’s right to prevent any owner, trainer or customer from attending a meeting. I have done so in the past and would do the same again whenever necessary.”
