A locksmith has discovered Britain's worst TOILET - after breaking into a house inhabited by squatters.

Rio Beardmore, 48, found the disgusting loo after being asked to force his way into a property owned by a friend after the occupiers refused to answer the door.

He said that a number of drug addicts had been living inside the building - letting it fall into a shocking state of disrepair.

But no room was worse than the toilet - with a vomit-inducing picture appearing to show mounds of faeces bulging from the loo.

The excrement seems to have spilled over onto the floor, landing on discarded clothes and carpet.

Rio said: "It stank - and I got bitten on the face by a bug. There must be something living in there.

"I've been doing this job for years - I thought I'd seen it all. It was the worst. The room was covered in s***.

"It was a baking hot day, around six months ago.

"This young copper walked into the house and asked if everything was secure. I said: 'There's something you need to check in the bathroom'.

"He walked in and shouted: 'You b******!'."

The squatters were eventually turfed out of the property in Stoke-on-Trent, Staffs, and the locks were changed.

The nauseating image has echoes of an infamous scene in the 1996 film 'Trainspotting'.
