Counter-Extremism Strategy

Lord Mendelsohn Excerpts

Thursday 12th February 2026 Grand Committee

[Lord Mendelsohn (Lab)]

My Lords, I congratulate the noble Lord, Lord Goodman of Wycombe, on introducing this debate. A serious discussion on this is long overdue, and I thank him for all his work and leadership on this and the many colleagues who I am looking forward to hearing who have been very involved in it as well. I declare my interest as a trustee of the Hofenung Foundation and as someone who has been deeply concerned about the growing extremism crisis in our country. We face a rapidly accelerating threat. We see this in the historic levels of antisemitism and anti-Muslim hate, the surge of Prevent referrals, the unprecedented normalisation of conspiracy theories and the rising tolerance, particularly among younger groups, of political violence. These are not isolated indicators; they are symptoms of a weakening social fabric and declining democratic resilience.

The most disturbing thing is that we are flying blind. We are confronting a fast-evolving, increasingly organised and sometimes foreign-backed extremism ecosystem without a national counterextremism strategy of any kind. We make a profound mistake when we conflate extremism with terrorism. Terrorism is the violent end point, but extremism is the infrastructure, the ideology, the recruitment ecosystem, the conspiracy culture, the dehumanisation and the democratic erosion that makes violence possible. Contest is an excellent counterterrorism strategy, but it was never designed to address the harms that sit below the terrorism threshold, where extremist groups currently operate with impunity. We have reached a point where extremist organisations—far left, far right, Islamicist—can radicalise children, spread dangerous ideological propaganda and mainstream hate on the streets and online without breaking any law because the law does not yet capture hateful extremism as a category. This is untenable.

What do we need to do? First, we need a clear operational definition of extremism, and I hope the Minister can confirm that the existing one announced by the previous Government still stands. It will be important to have his reflections on whether the Government will accept that it should include reference to hateful extremism. Secondly, the Government must close the legislative gaps. As set out in the report Operating With Impunity, we need hateful extremism proscription orders for extremist groups that sit below the terrorism threshold but whose actions are demonstrably harmful. Other democracies such as Canada and Germany already do this. Following the horrendous Islamicist terrorist attack in Australia, its Government are taking steps to list proscribed groups in regulations, where this can be applied. We cannot allow extremists to operate freely simply because the law has failed to keep pace.

Thirdly, the Government must fund ideological challenge programmes. When asked about what kinds of counterextremism programmes the Home Office funds outside Prevent, Jonathan Emmett mentioned at the Home Affairs Select Committee that the Government had made a significant sum available for protective security at places of worship. I welcome such funding—although not that much, as it is a sign of real failure that we must produce money for security in those places; it would be nice if it went down, rather than kept going up—but it is a mistake to equate protective security with counterextremism programmes. We must challenge extremist narratives, online and offline, support vulnerable individuals and build resilience against conspiracy theories, dehumanisation and hate.

The data shows a country fragmenting with extremism metastasising into the cracks, online in civic spaces, on our streets and in community relations. If we fail to act now, the social, political and security-related costs will only deepen. This debate is about safeguarding the integrity of our democracy and the safety of our communities in the kind of country we aspire to be. I hope that the Minister will agree that we need a muscular and values-driven counterextremism strategy. It is not optional; we must do it, and now.
