Home Secretary Theresa May will use her speech to the Tory party conference to set out a package of measures to tackle Islamist extremists.
Under the plans, new "banning orders" would allow the authorities to outlaw extremist groups, even if they did not pose a terrorism threat.
Hate preachers could be targeted with "extremism disruption orders (EDOs)", which would allow the courts to restrict the movement and activities of individuals to prevent the risk of violence or public disorder.
The two new orders will be included in the Tory manifesto for the next election, but Mrs May will also set out a new cross-government strategy to tackle extremism.
Home Secretary Theresa May said the Crown Prosecution Service is reviewing the case against Ashya King's parents.
During a statement in the House of Commons, Ms May said:
I understand the CPS are indeed reviewing this issue as we speak.
The Home Secretary has said the perpetrators of child sexual exploitation in Rotherham "must be brought to justice".
Theresa May told MPs that although it would not be appropriate to discuss ongoing investigations "in detail", there are a number of investigations underway "covering several hundred victims" in South Yorkshire.
Home Secretary Theresa May has called the Rotherham scandal "a complete dereliction of duty".
Answering an urgent question in the House of Commons, May told MPs the report showed "the appalling failures of Rotherham Council and by the police and other agencies to protect vulnerable children."
"It makes for shocking reading," she added.
Home Secretary Theresa May has said that South Yorkshire Police Commissioner Shaun Wright should "heed" calls for him to resign.
She said it was not her job to "hire and fire police commissioners," but added that Mr Wright "has real questions to answer".

Britain's child sex abuse investigation body needs more access to phone and internet records so it can better investigate crimes, Theresa May has said.
The Home Secretary spoke ahead of reports the Government is due to pass emergency laws requiring phone companies to store text, call, and web use data.
Her comments came after it emerged the Child Exploitation and Online Protection Centre (Ceop) made fewer arrests last year than the previous year.
A review of undercover policing announced by the Home Secretary will initially focus on the Metropolitan Police's Special Demonstration Squad, a top secret unit that operated for 40 years before being disbanded in 2008.
It will also look at the activities of the National Public Order Intelligence Unit, which is not part of the Met but undertook similar tasks.
The investigation will look at a variety of issues, including what kind of undercover policing was undertaken, whether evidence relevant to criminal cases was kept secret and whether any convictions may be unsafe because undercover police activity was not revealed.
Speaking in a debate on passport delays, the Home Secretary, Theresa May MP, told the House of Commons:
Her Majesty's Passport Office is dealing with the highest demand for passports for 12 years, while the surge in demand usually experienced during the summer months started much earlier in the year. As a result, a number of people are waiting too long for their passport applications to be processed.
Ms May was speaking in a Commons opposition day debate called by Labour, in which many MPs highlighted the plight of constituents experiencing passport delays.
The Home Secretary has described forced marriage as "cruel and unacceptable" and said new laws will which come into effect today show the practice "will not be tolerated" in the UK.
In an exclusive blog for Good Morning Britain, Theresa May said laws were needed because the "scale of the problem is staggering".
We want to send a clear message that forced marriage is cruel and unacceptable and will not be tolerated.
The individual stories are heart-rending. In one tragic recent case, a 17 year woman was taken to Turkey – she thought she was going on holiday, but instead she was forced to marry.
She was a bright, ambitious young woman who planned to go to university to study law. But suddenly her life had become a total nightmare. The marriage was horrifying, with sexual, mental and physical abuse.
