Both directions of the M4 between Junctions 12 and 13 are closed after a horse was found loose on the motorway.

Thames Valley Police and traffic officers are on the scene, working to identify the animal’s owner and determine the safest way to remove it.

Authorities have said the welfare of the horse is being treated as a priority throughout the operation.

The closure is being maintained as a precaution while the situation is managed.

Motorists are advised to avoid the area until the motorway can be safely reopened.

Diversion routes are in place for road users traveling westbound and eastbound, with updates expected once the horse has been safely removed.
