MI5 'spy': Disqusted & ashamed of myself

'Anger, wife split and booze' fulled motive

- DAN WARBURTON

A SECURITY guard caught in an MI5 sting after selling secrets to Russia yesterday denied he was a spy, claiming: "I was an obstinate brat."

David Smith, 58, hoarded documents and was caught filming a man named "Dmitry" he thought was a Russian "traitor" where he worked at the British embassy in Berlin.

But it was actually an undercover sting and the man was a British spook.

Smith, of Paisley, told a court yesterday: "I'm disgusted with myself.

At the time I didn't think about what I was doing. I'm disgusted with myself and ashamed of what I've done.

"I was like an obstinate brat. I had not planned to do anything like that, it was just something that happened." Smith had also been approached by an MI5 "agent provocateur" named Irina, posing as a GRU Russian intelligence officer.
