Motorists are still being urged to avoid a section of a Kent motorway after a day of traffic misery following a diesel spillage.

A lorry's fuel tank split all over the London-bound carriageway of the M20 between junction 4 (West Malling) and junction 3 (Wrotham Heath) at around 6.50am.

Lanes were closed while the spillage was cleared up, causing "heavy congestion".

Three lanes of the motorway were then shut to allow resurfacing of a 20-metre stretch.

It is expected that one lane will reopen at around 4.30pm, but police say it would be another two hours until the other two lanes are reopened.

Morning rush-hour problems were heightened by another incident further east on the same motorway when a truck hit the central reservation between junction 10 (Ashford) and 11 (Hythe).

A lane was closed in both directions for repairs to the barrier.
