The Grand National has been met with delay after disruption from animal rights activists at Aintree racecourse. The start time of 5.15pm has been pushed back after confirmation of an "indefinite hold".
ITV broadcast footage showed a number of protesters attempting to scale fences around the perimeter of the course, as police sought to keep them out. Ladders were used to try and climb into the grounds shortly before the main race was due to get underway.
More scenes screened on TV appeared to show some activists on the course itself, with suggestions from those speaking on ITV that some had been hiding in the fences. There were claims that activists were trying to "glue themselves" to the obstacles.
