The nightmare of George Orwell's 1984 has become a reality - Big Brother is now in the shadow of the author's former London home.  It took a bit longer than he predicted but his vision of a society where cameras and computers can spy on every person's movements is now here.

According to the latest studies, Britain has a staggering 4.2million CCTV cameras - one for every 14 people in the country - and 20 per cent of cameras globally. It has been calculated that each person is caught on camera an average of 300 times daily.

On the wall outside his former residence - flat number 27B - where Orwell lived until his death in 1950, an historical plaque commemorates the anti-authoritarian author. And within 200 yards of the flat, there are 32 CCTV cameras, scanning every move.

Orwell's view of the tree-filled gardens outside the flat is under 24-hour surveillance from two cameras perched on traffic lights.

The flat's rear windows are constantly viewed from two more security cameras outside a conference centre in Canonbury Place.

In a lane, just off the square, close to Orwell's favourite pub, the Compton Arms, a camera at the rear of a car dealership records every person entering or leaving the pub.

Within a 200-yard radius of the flat, there are another 28 CCTV cameras, together with hundreds of private, remote-controlled security cameras used to scrutinise visitors to homes, shops and offices.
