With long queues of lorries, they were scenes you would usually expect to see in relation to Operation Stack.

But last night there was traffic chaos on the M20 for a different reason.

The motorway was shut London-bound after nine horses trotted onto the carriageway at the bottom of Wrotham Hill, near J2.

They were reported to police at 12.20am, leading to a rolling road-block being put in place.

By 2am they had been secured in a nearby field, and the motorway was reopened shortly afterwards.
