A survivor of the fatal coach crash near Heathrow Airport, who helped save two of his fellow passengers, has spoken of "carnage and mayhem".
Peter Grimes recalled the bus swerving and bracing himself
Glaswegian Peter Grimes, 45, was on his way to visit a friend in Dundee when the crash happened on Wednesday night.
The builder, who lives in Fulham, said he braced himself against windows and seats as the bus crashed.
A man and a woman died in the crash. The woman was later named as Chris Toner, 76, from Monifieth, near Dundee.
Mr Grimes said that on the M25 slip road he anticipated a problem at the bend.
"I braced myself against the seats next to me," he said.
"I'm still looking towards the front of the bus and as he came round, he pulled to the right so it swerved and then he pulled to the left.
"As the bus sharply went left, the wheels went up," he said.
Mr Grimes said he must have lost consciousness for a few minutes.
When he woke up, "it was mayhem, it was carnage".

Mr Grimes helped carry one of the men next to him along the bus so emergency service personnel were able to lift him out of a hatch.
"I went back and I got the second gentleman and I got him out as well," he said.
Despite his injuries, which included a broken collar bone and multiple lacerations, Mr Grimes said he thought he was "very lucky".
He said: "People were maimed, people were trapped, they had legs trapped and arms trapped underneath the bus."
The man in the seat in front of him had no pulse on his neck and blood coming out of his head.
"It was devastating," Mr Grimes said.
Despite having nightmares over the past two nights, while still in hospital in Hillingdon, Mr Grimes said he had not been put off travelling by coach.
"As soon as I'm ready, I'm going up to Glasgow to see my mother. I've always enjoyed travelling on them, especially at night."
He added: "The hospital, the staff - from the guy who makes the tea, the surgeons, right up to the nursing staff - everybody has been absolutely amazing."
Twenty-three of the 67 passengers remain in hospital, some of whom have lost limbs.
