Jean Charles de Menezes marksman: ‘I thought we’d die’

“I’m expecting an explosion at any moment; he’s gonna blow. We’re gonna die. But that’s the nub of it.

“If I don’t do something now, we are all going to die.”

On 23 July, Scotland Yard confirmed Mr de Menezes was not connected to the 21 July attacks.

Dame Cressida Dick, who was promoted to Metropolitan Police commissioner in 2017, led the operation in which Mr de Menezes died.

A jury cleared her of any blame in his death at the end of the prosecution of the Met under health and safety laws.

Sir Tony Blair, who was prime minister at the time, recalled he was in a bilateral meeting with the Chinese president when he received news of the 7/7 bombings.

“I got handed a piece of paper saying there’d been a series of incidents on the London Underground,” he said.

“At that time, I didn’t have any more information about it. The moment you get passed a note like that, you expect the worst.”
