Large stretches of the M25 have been closed due to flash flooding.
The motorway has been shut between J7 and J7 near Reigate in the clockwise direction.
A further three of four lanes are shut going anti-clockwise, while the M23 southbound is also closed from J7 to J8.
The source of what is amounting to huge delays is flash flooding caused by a thunderstorm was brought torrential rain to the area.
Images from the M25 show some cars stranded in the standing water, while queues are very heavy on approach to the flooding.
