Labour would reverse cuts to the police planned for next year if it wins power in May, shadow home secretary Yvette Cooper has said.
The party would also scrap police and crime commissioners (PCC) to pay to protect women's refuges.
Shadow Home Secretary Yvette Cooper has said that South Yorkshire Police Commissioner Shaun Wright ought to stand down, but stressed that reforms were needed too:
She also called for the "child abuse inquiry to start urgently".
Rape cases that are dropped by the police would be reviewed under Labour plans to boost the rights of victims, Yvette Cooper will say.
The shadow home secretary will pledge to give victims a "strong voice" and warn the low rate of allegations being pursued is "shameful".
In a speech to the Fabian Society, she will insist Labour is focusing on reforms that give more power to individuals and communities but stand ready to make tough decisions about making savings.
"Just as in the criminal justice system, across our public services, ministers are driving fragmentation, reorganisation and competition just at a time when local services need to collaborate more to deliver better services and save money too", she is expected to say.
Parents, schools, sports clubs and other organisations caring for young children need to have "confidence in the vetting and barring system" so they know employees pose no threat to youngsters, the Shadow Home Secretary has said.
Yvette Cooper hit out at Home Secretary Theresa May who she claimed was "warned repeatedly" that changes she made to vetting and barring laws "left major loopholes in the system".
Shadow home secretary Yvette Cooper will warn the Government it must not "bury its head in the sand" as she calls for reforms to keep up with ever-evolving cyber-crime.
In a speech to the Demos think tank, Ms Cooper will call for a new national strategy for tackling online fraud, tougher action to tackle online child pornography and an overhaul of parliament's Intelligence and Security Committee, which keeps a check on the work of the intelligence agencies.
"The oversight and legal frameworks are now out of date. That means we need major reforms to oversight and a thorough review of the legal framework to keep up with changing technology," she is expected to say.
"Above all we need the Government to engage in a serious public debate about these new challenges and the reforms that are needed."
Labour wants new powers for police and security services to crackdown on cyber-crimes such as child pornography and terrorism, but only with extra checks on how crime agencies are using sensitive data, the shadow home secretary is set to say.
Technological developments have sparked a wave of new types of crime and a 30% hike in recorded online fraud is just the "tip of the iceberg", Yvette Cooper will warn.
But fears about abuse of information in the wake of leaks by ex-US National Security Agency contractor Edward Snowden, which revealed widespread spying by Government listening post GCHQ, means new safeguards are needed to protect privacy.
Much stricter controls over access to private data must be introduced to give the public confidence amid fears about the way information can currently be accessed and used, she is expected to say.
Shadow home secretary Yvette Cooper has slammed the Government's immigration bill as a "car crash", accusing David Cameron and Theresa May of being scared of their own backbenchers.
Ms Cooper, who said she sympathised with the amendment, said ministers "sat on their hands" instead of voting against Mr Raab's amendment because they were worried about their backbenchers.
The Labour MP accused the Home Secretary of acting in the interests of the Conservative Party rather than in the interests of the country and suggested she had lost control of her own policy.
"I have to say the Immigration Bill has been a complete car crash for the Home Secretary. She and the Prime Minister launched this as their flagship Bill," Ms Cooper said.
"This was the pride and joy of their legislation and yet they have been hiding it away for months. We have had months when the Immigration Bill was nowhere to be seen, when they wouldn't bring it back because they were so scared of their own backbenchers."
Shadow home secretary Yvette Cooper has said that the government's decision to offer refuge to some Syrian refugees showed that "compassion and common sense have won through".
The Labour politician said the coalition has "completely changed their position since seven days ago":
The shadow home secretary Yvette Cooper has said Twitter "must get their act together" after football pundit Stan Collymore complained the site should do more to tackle abusive tweets:
Shadow home secretary Yvette Cooper said the actions of PC Keith Wallis, who has pleaded guilty to misconduct in public office in relation to the "plebgate" affair, risks "casting a shadow over the excellent work police officers do day in, day out".
