Mr Biddle interview

He was standing opposite Mohammad Sidique Khan, on a westbound Circle Line Tube train, when the suicide bomber reached into his rucksack and detonated his explosives at Edgware Road, killing six other people.

Mr Biddle, from east London, lost both legs, one eye, his spleen and a huge amount of blood. He was in hospital for almost a year.

When he was first taken to St Mary's Hospital in London after the blast, his injuries were so severe the medical team did not expect him to survive.

'Heart stopped'

A year on, vivid memories of that day still haunt Mr Biddle.

I just believed that I would die and I still can't believe that I didn't Danny Biddle

"Every time I shut my eyes at night I'm back in that tunnel. I can hear those people screaming, I can smell the electrics and the burning metal. It doesn't go away," he said.

"My heart stopped three times on the day. I just didn't think I was going to get out of there alive."

Mr Biddle said he had made eye contact with Khan, who was seated on the train, moments before the bomb went off.

He said: "There was just a massive flash like a million camera flashes going off, white noise like when you tune a radio in, and with the force of the carriage expanding and compressing very quickly it blew me out of the train into the tunnel wall and I was lying next to the train in the crawl space.

"I just believed that I would die and I still can't believe that I didn't. For all medical intents and purposes I should have."

'Horrific injuries'

Paramedic Graeme Baker was one of the first people to go to Mr Biddle's aid in the tunnel and helped save his life.

"He had obviously been blown out of the train and sustained quite horrific injuries," Mr Baker said.

"I was quite worried that he would become unconscious at any time because he lost an awful lot of blood and without having that replaced it would be easy for him to fall into unconsciousness or even die down there."

Mr Biddle was rushed to accident and emergency, and four surgeons operated on different parts of his body for more than five hours.

At one point his heart stopped and to get it going again they had to open his chest and massage his heart manually.

Now he has left hospital Mr Biddle is looking to the future - planning his wedding and moving into a new house.

"I've got to get used to life again," he said.

"It's going to be a big adjustment to be at home and doing things for myself again. I can't wait but it's going to be quite frightening.
