The A4 is closed in both directions due to a jackknifed lorry and fuel spillage between the B4003 (West Kennett) and High Street (Marlborough).
The fuel tank on the lorry has ruptured and there is a large diesel spill on the road near to the Clatford junction.
The road is likely to remain closed for a considerable time.
