Former IRA terrorist Dessie Ellis has admitted in a new Mail podcast launching today that he was lucky to be cleared over his alleged role in the dual bomb attack on London in 1982 that left 11 people dead.
The ex-bombmaker, 71, was extradited to Britain in 1990 to face charges of building the devices that killed 11 soldiers.
On the morning of July 20, 1982, a nail bomb was detonated in a car in Hyde Park as soldiers of the Household Cavalry were passing on their horses, seven of which died.
Two hours later, a second device exploded underneath the bandstand in Regents Park, as members of the Royal Green Jackets were performing to a crowd.
Speaking in an interview with the Daily Mails executive editor in Ireland, John Lee, on From Bomb to Ballot: The History of Sinn Féin, the one-time TV repair man, now 71, says he was acquitted because of a loophole.

He says: Because my prints were in a certain dump that I was connected to incidents in England, that was what they were trying to prove.
But there was a loophole that you had to be made fully aware of where items were going and we used the argument to say that items that were found in England, if I had had my hands on them, I couldnt tell where they were going to go.
I got acquitted in the Old Bailey and I was sitting there, and there was a guy sitting over reading the paper and the big headline on the paper was "This man won the lotto."

As well as those who were killed, the other soldiers in the procession were among at least 51 people - including civilians and police officers - who were injured.
The members of the Household Cavalry were taking part in their daily Changing of the Guard procession from their barracks in Knightsbridge when they were hit by the blast.

Asked in the astonishing new podcast what his exact role was in the Irish Republican Army, Mr Ellis says: Well, I dont want to go into too much, but Id say, look, I was in the Republican movement.
I had a role in the Republican movement and that role, I fulfilled to the best of my ability. And, it was, I suppose, successful to a certain point.
In 1983, Mr Ellis was sentenced to ten years in prison in Ireland after being found guilty of possessing materials used to make explosive devices.
After being released from prison, he reported back to the IRA but then decided to go into the politics because it was too hot to remain a criminal.
He says: Well, I reported straight back in, first off, to the Republican movement.

And then, after a period, I decided that I was just far too hot that I couldnt move without having a problem.
So I then decided, then, at that stage, and we sort of collectively decided that I would go into politics.
