A cow closed two lanes of the M4 after wandering on to the motorway.

Gwent Police sent officers to the scene to deal with the animal, on the westbound carriageway near the Prince of Wales Bridge in Monmouthshire.

But by the time they arrived, the animal had made its way back into the field it had escaped from.

Traffic Wales said the road was fully open again by 20:30 BST.
