In the centre of the image stands an invisible man - labelled MI5 - and his invisible dog. Thatcher gestures at them holding a folder labelled 'Bridge report'. On the right, a miner, a woman holding a folder labelled 'Labour Party', a man holding a CND sign with a peace symbol, and an unidentified man bleeding from his finger are attacked by the invisible dog. On the left of Thatcher stand three former Prime Ministers.
Context: allegations that the secret service had tried to destabilise Labour Governments and left-wing movements were denied by Thatcher and three former Prime Ministers (Source: Gibbard's Double Decade Omnibus)
