The Everton area has more than 40% unemployment and crime and antisocial behaviour are significant problems.

Mr Cameron returned to his “broken Britain” theme when explaining that the Conservatives were committed to “second chances”.

He added: “How do we build a strong society to help those who have fallen through the cracks, and give them a second chance?

“This is exactly the kind of organisation that inspires me, young lads who were living a life of crime who now have a job.

“We’ve got to get things moving and get jobs going.

“When it comes to people who have been unemployed for a long time, I believe there is a place for social enterprises like these. Where we are sitting now, four months ago, was nothing.

“Now it’s employing 40 people.

“I believe we have to mend the broken society and concentrate our efforts in parts of the country where unemployment is the highest and family breakdown is the worst.”

Mr Cameron left Home to visit Families Fighting for Justice, where he met Gee Walker – mother of murdered teenager Anthony Walker – as well as Helen Newlove, widow of Garry Newlove, who was kicked to death by teenage thugs outside his Warrington home in 2007.

Jean Taylor, who set up the charity after her 27-year-old daughter, Chantel, was brutally murdered in Wirral in 2004, said Mr Cameron and shadow Home Secretary Chris Grayling had listened attentively to their calls for improved support for the loved ones of victims of crime.

Mrs Taylor added: “They wanted to meet with us and hear our opinions.

“The organisation is non-political but we will go anywhere and talk to anyone who can help change be made.”
