Rape victims and abused children could face greater protections when questioned in court under plans to be drawn up by Keir Starmer.
The former chief prosecutor told ITV News the current justice system is "not fit for victims".
He added: "Most people, particularly vulnerable victims or witnesses don't have the confidence to come forward because they don't think that criminal justice can help them."
Mr Starmer said he would advise Labour on introducing legislation, should it win power in 2015, to give greater protections to vulnerable witnesses in court.
As director of public prosecutions, Mr Starmer had to be politically neutral. But since he stood down, there have reports that he is planning to move into politics.
It is essential that the police, courts and other agencies do more to ensure that the rights of people affected by crime are at the heart of the criminal justice system, the chief executive of independent charity Victim Support said. Javed Khan added:
The Government has considerably improved the support given to vulnerable victims and witnesses in court, a spokeswoman for the Ministry of Justice has said, as plans for greater protection for victims were unveiled. The spokeswoman added:
Shadow justice secretary Sadiq Khan has said proposals to give victims of abuse better protection, would give the public greater confidence in the criminal justice system. He said:
Victims are entitled to have their rights clearly set out and enforced by a victims' law, former chief prosecutor Keir Starmer has said, as plans for greater protection are drawn up.
Mr Starmer said: "This is a golden opportunity to recast the criminal justice system as a criminal justice service fit for victims. But it will only succeed if there is an attitude-shift across criminal justice.
"Those delivering criminal justice have been on the back foot for far too long when it comes to victims' rights."
Rape victims and abused children could face greater protections when questioned in court under plans to be drawn up by former chief prosecutor Keir Starmer, Labour said today.
Mr Starmer, director of public prosecutions until earlier this year, will also look at making it a legal obligation for the police and prosecutors to keep crime victims informed about the progress of investigations.
There have been a number of high-profile cases where vulnerable witnesses have faced the harrowing ordeal of having to relive their experiences in detail under cross-examination in court.
Today, Mr Starmer said he would advise Labour on introducing legislation, should it win power in 2015, to give greater protections to vulnerable witnesses in court.
New sexual abuse allegations against Stuart Hall come a week after the former presenter's jail sentence was referred to the Court of Appeal for review, following complaints it was too lenient.
Hall was last month sentenced to 15 months in jail after admitting 14 counts of indecent assault, relating to girls aged between nine and 17.
The Attorney General referred the disgraced broadcaster's case after receiving about 150 complaints arguing the sentence was "unduly lenient".
One of the Hall's victims, Susan Harrison, told ITV News she kept the abuse secret for many years for fear of not being believed.
Police are investigating new sex crime allegations made against Stuart Hall.
The former broadcaster was jailed last month for sex attacks on children - the youngest, aged 9. Hall, who is 83, is serving 15 months for those offences.
Lancashire Police told ITV: "We can confirm that we have received further allegations against Mr Hall and we are working closely with the Crown Prosecution Service to determine the most appropriate course of action."
"We take all allegations of sexual abuse seriously and we would encourage people with any information about sexual abuse or who has been a victim of sexual abuse to come forward and report their concerns."
Teenage victims of domestic violence and abuse will be officially recognised as victims under Government plans, Nick Clegg will say today.
The Home Office is widening the definition of domestic abuse to include those aged 16 and 17 as well as a wider range of coercive or threatening behaviour, Clegg will say.
But campaigners warned that more funding is urgently required to help support the highly vulnerable victims.
A Young People's Panel will be set up by the children's charity the NSPCC to work with Government on domestic violence policy.
Louise Casey, Head of a new Troubled Families Team, has said that some of the findings into England's most troubled families was 'difficult' and 'harrowing'.
Ms Casey told Daybreak that families from a troubled background of sexual and violent abuse often don't know how to parent properly.
