Three out of four lanes are closed on the M25 in Surrey between J10 (Cobham) and J9 (Leatherhead) due to an overturned trailer that was carrying a boat. 

National Highways warned drivers are facing "severe delays", with reports mentioning 120 minutes above normal journey times and congestion of approximately nine miles, almost back to J12 (the M3 Junction). 

A "specialist recovery" team is currently working at the scene, one lane remains open.

It's not known if anyone has been hurt, or when lanes two, three and four will reopen.
