New measures to protect children and restrict the activities of fanatics will be rolled out in a crackdown on extremism.

The Counter-Extremism and Safeguarding Bill will include powers to intervene in unregulated schools which "teach hate" and "drive communities apart" Vetting rules are expected to be adapted to enable employers to check whether an individual is an extremist and bar them from working with children.

Ministers will consult on rolling out a civil order regime to "restrict extremist activity", as well as new powers to enable the Government to step in when councils fail to tackle extremism.

The legislation aims to help deliver on the Tories' manifesto pledge to tackle all forms of extremism, so "our values and our way of life are properly promoted and defended".

The Bill follows a programme to tackle extremism and radicalisation announced last year.

It proposed introducing banning orders for extremist organisations who use hate speech in public places, but whose activities fall short of proscription, and new powers for authorities to close down premises used to support extremism.

Rachel Robinson, of campaign group Liberty, said: "We already have criminal law to deal with terrorism, hate speech and the incitement of violence, so all that's left for these proposals to ban are people and views that the Government disagrees with.

"Powers to radically curb free speech will be placed in the hands of ministers who paint their political opponents as extremists and 'threats to national security'.

"The fact that the Government is still struggling to define the 'extremism' they want to ban should be a clear indication that this legislation has no place in a liberal democracy."

Simon Blackburn, chairman of the Local Government Association's Safer and Stronger Communities Board, said: "Councils have built up considerable experience in dealing with extremism and the impact of extremist activity on their communities.

"Local authorities now need help with the resources they need to build local capacity to counter extremist activity.

"With the Prevent Duty introduced last year, the Counter-Extremism Strategy published last October and the Louise Casey review about integration ongoing, councils are working with a number of different government departments and Whitehall also needs to join up and bring together these different programmes in a way that works better for local authorities.

"Further legal powers will help to tackle some extremist individuals and organisations and with protecting communities from them. However, on their own they aren't the solution and more resources and better guidance is also needed."
