Sex workers in a major British city are said to be selling their bodies for as little as £4 - with prostitutes blaming an influx of Eastern European competitors for pushing down prices.

Men can often be seen casually looking for women in Liverpool's notorious red light district - where one worker's brutal murder shocked the nation and another had her teeth knocked out with a baseball bat.

The city is home to the second highest concentration of sex workers in the country but tensions are rising between the traditional workers and an influx of women from Eastern Europe.

It is claimed the immigrants are driving down prices, according to the Liverpool Echo.

Speaking on a BBC Three documentary, a man named Liam, who lives on the heart of the red light district and claims to look after the workers, said: 'Some of the girls give it away for £4.

'I'm not a pimp. I have nothing do with any of their money.

'They just buy me drinks, food, they don't pay me. I just watch their backs to be honest with you.'

During the course of the programme he is forced to fight off one punter who refuses to leave one prostitute alone.

The documentary tells the story of crack addict Natalie, who works on the streets to fund her habit.

Natalie plies her trade on Sheil Road, which has become synonymous with the city's sex trade and is close to where prostitute Anne Marie Foy was killed in 2005.

She said: 'Obviously I had to lower prices to get them there.'

Natalie then reveals how and 'the only times somebody opens their arms to me is when dragging me on a bed.

'What's normal to me is getting up, getting dressed and getting to have sex with a different man day in, day out.'

A man named Jack, who lives with Natalie, blames Eastern European sex workers for flooding the market and slashing prices.

He claims women come from as far as Serbia and Croatia and sell sex for rock bottom prices.

He said: 'They're absolute stunners. But the local girls... Sometimes I have to lend them my teeth.'
