UK intelligence agencies are closely monitoring the rise of far-right extremism in Germany, where authorities estimate there are 60,000 individuals with extremist potential. This development is testing the resilience of European security cooperation and raises concerns about cross-border radicalisation.
Officials in Whitehall have described the situation as a growing concern for domestic security, noting the porous nature of borders within the Schengen area and the ease with which extremist networks can operate across jurisdictions. The figure, provided by German domestic intelligence, represents those deemed capable of committing politically motivated violence.
The assessment has prompted increased information-sharing between MI5, the Bundesamt für Verfassungsschutz, and other allied agencies. Sources indicate that the threat is not merely hypothetical: several individuals on the German watchlist have been identified attempting to travel to the United Kingdom, though none have succeeded in recent months.
The far-right milieu in Germany encompasses a spectrum of groups, from organised political parties such as the Alternative for Germany to looser networks inspired by international white supremacist ideologies. The most concerning element, according to analysts, is the radicalisation of individuals within the German security services themselves. Reports suggest that up to 600 members of the police and military have come under investigation for far-right activity.
This internal dimension poses a unique challenge for European security frameworks that rely on trust between national institutions. The UK’s decision to leave the European Union has further complicated intelligence-sharing arrangements, though bilateral ties remain robust. A senior MI5 officer described the situation as a test of the post-Brexit security partnership.
The response from German authorities has been assertive. The interior ministry has accelerated efforts to prosecute hate speech and disband extremist groups. However, legal obstacles remain, including the protection of political speech under German law and the difficulty of proving conspiracy to commit violence.
The 60,000 figure is the highest recorded in a decade and represents a doubling since 2016. The COVID-19 pandemic provided fertile ground for radicalisation, with anti-lockdown protests serving as a gateway for extremist ideas. The war in Ukraine has also been exploited by far-right actors seeking to recruit among those sympathetic to Russian narratives.
From a strategic perspective, the far-right threat is qualitatively different from Islamist terrorism. It is more diffuse, with a lower barrier to entry and a greater reliance on lone actors inspired by online propaganda. The recent attempted coup by a group calling itself the Reichsbürger movement demonstrated the capacity for organised violence, though it was poorly executed.
The UK’s own far-right landscape is smaller, but the potential for contagion is real. British intelligence is particularly concerned about the sharing of tactical knowledge and the radicalisation of British citizens visiting Germany. The National Extremism Tactical Coordination Unit has been tasked with monitoring travel patterns.
Institutional integrity is at stake. The fact that German security personnel are among those being investigated undermines public trust and demands robust internal vetting. The UK has implemented similar measures following the exposure of far-right sympathies within the Metropolitan Police.
European security frameworks were designed primarily to counter state-based threats. The rise of transnational far-right extremism forces a re-evaluation. The UK, though outside the EU, remains embedded in NATO and a host of bilateral arrangements. How it navigates this threat in concert with continental partners will shape the continent’s security architecture for years to come.
For now, the official advice to the British public is unchanged: the terrorism threat level remains at Substantial, meaning an attack is likely. But the quiet co-ordination between London and Berlin suggests that something more fundamental is being tested: the ability of liberal democracies to police themselves without compromising their principles.
