I saw this on my way into London didn’t think it had happened that early as the police were still turning people around on the coast bound carriage way and trying to organise them onto the off slip road with traffic coming out of London rather than using the on slip road. air ambulance was there with no queue London bound however you had the obligatory idiots rubber necking and when I looked later on there had been an accident London bound. Bit surprised they didn’t have the screens up when I went past as they had towed the rm wagon with the fire engine
