We want to hear from all those concerned about rising extremism - including charities working with communities affected by extremism, academics studying the issue and all those who work on the frontline to counter extremism.
The evidence we gather over the next 10 weeks will feed into a wide-ranging study of extremism to be published in spring 2019.
The aim of the study is to build understanding of extremism, in all its forms, in our country and give people the confidence to challenge it.
The Commission is asking crucial questions as part of the online consultation, including how Government can strengthen its response to extremism, what the scale of the problem is and how social media plays a role in spreading extremist ideas and activities.
The Call for Evidence comes after eight months in which the Commission has visited 13 towns and cities across England and Wales, begun a review of academic literature on extremism and met more than 400 counter-extremism experts and activists.
Sara Khan, Lead Commissioner for Countering Extremism, said:
"Extremism is thriving in some parts of our country, but we do not know the true scale of the problem and the full impact it is having on our society – what we do know is very likely to be just the tip of the iceberg.
"I know from meeting more than 400 experts and activists in 13 towns and cities across England and Wales over the last eight months that extremism is affecting not just individuals but also our communities and the very fabric our society.
"It is weakening trust in the very institutions we cherish, is undermining our democratic values and is inciting violence, hatred and hostility.
"Extremists appear increasingly professional and we have heard how they deliberately employ anti-racist and pro-free speech arguments, actively intimidate others and promote a warped us vs them mentality to shut down debate and spread hateful ideologies. They rely on social media to normalise conspiracy theories and disinformation. Brave counter-extremists who take them on suffer horrific abuse both online and offline.
"Despite the threat of growing extremism, we still lack a full picture of it in our country; and how best to counter it. Extremism is a complex and multi-faceted issue. It is a whole society problem and requires a whole society response. It is imperative that we develop a pro-active and proportionate response. The first step however is to improve our understanding of extremism and to give everyone the confidence to challenge it.
"That’s why my Commission is calling on NGOs, academics, all those who work in counter-extremism and everyone concerned about this growing threat to take part in our Call for Evidence.
"It is essential we defend our fundamental freedoms and rights from those who seek to undermine them. All of us – families, communities, schools, civil society, academia and government have a part to play in defeating extremist ideas and activities and my Commission will support society to do this."
As part of the Call for Evidence, the Commission is asking for:
Personal accounts of extremism
People’s views on the Government’s definition of extremism
Insight into the objectives and tactics of extremists and the scale of extremism in England and Wales
Evidence of the harms extremists cause to individuals, communities and society at large
How government should strengthen its response to extremism
Social media’s role in spreading extremism
The Commission is also:
Writing to Government departments asking them to share information about extremism (as agreed in the Commission’s Charter)
Commissioning new research on the Far Right and Islamist extremism from leading experts
Seeking testimony from victims of extremism and those countering extremism
Commissioning a nationally representative survey to gauge the public’s views on extremist ideas and behaviour.
