Former Enfield Council leader Jeff Rodin was a survivor of the Piccadilly Line train targeted by terrorists between King's Cross and Russell Square on Thursday morning.

The 55-year-old Labour Group leader, who boarded the train at Finsbury Park and was seated just two carriages away from the bomb, described the immense shock and relief' he felt after walking away from the incident unscathed.

He said: "There was a bang and the train came to a sudden stop and dropped as if we were derailed.

"It went pitch black and then dust and smoke came pouring into the carriage."

Despite hearing the sound of breaking glass and people screaming, he and the other passengers in his carriage did not realise it was a bomb.

He was led from the train by Underground staff and phoned his wife and son.

"He told me there had been more than one incident. I got to work and found out they were bombs.

"It hit me later that I was on a train where 21 people were killed it was a mixture of shock and relief."

With public transport in chaos it took Cllr Rodin three-and-a-half hours to walk from his workplace in Holborn to Turnpike Lane.

He added: "People just got on with it, and everyone walking was fairly cheerful."
