A crash has bought the M25 to a standstill.

The Bell Common tunnel - between J27 and J26 - has had all lanes stopped anti-clockwise due to a broken down HGV and spillage.

Traffic is building in the area as a result with five miles of slow moving traffic on approach.

Update 11.53pm: Lanes three and four are now open with traffic flowing past the scene. Lanes one and two remain closed to facilitate recovery. 

It is taking an extra 40 minutes to get past the incident, with traffic slow back to J28.

Updated 12.53pm: All lanes are now open. There are ten miles of tailbacks and getting through will add an extra 70 minutes onto your journey time.
