There are problems on Kent's motorways this morning causing delays for commuters.

On the M20, an accident involving a car and a lorry on the eastbound carriageway is affecting traffic near Maidstone between J4 A228 Castle Way (Leybourne/Snodland) and J5 (Aylesford).

There are no reported injuries. Three of the four lanes remain open.

Meanwhile one of the two Dartford Tunnels is closed causing big delays for M25 traffic heading towards Purfleet from Kent.

The right hand tunnel is closed. The left hand tunnel is open, but it has a 4.8 metre height restriction.

There is congestion for traffic travelling anti-clockwise between J2 A2 (Dartford) and J31 A1306 (Lakeside/Purfleet).

The closure is due to a broken-down horse-box in the tunnel.
