Extremism is defined by the Government as “vocal or active opposition to fundamental British values, including democracy, the rule of law, individual liberty and mutual respect and tolerance of different faiths and beliefs”. 

There is limited participant research that looks at the causes of extremism, how individuals are radicalised, or the ways in which it might be prevented. Therefore little detail is known about the early processes and pathways to radicalisation. However the research base does show that there is no typical extremist or single process of radicalisation. 

Factors Relevant to Islamic Extremism
Academic research has identified five factors that may be associated with those who come to hold extremist Islamic views:

  • Uncertainty around identity
  • Ideological factors
  • Personal circumstances
  • Grievances about foreign policy or media representation
  • Age and gender factors

The UK Government response
The UK Government’s counter-terrorism strategy, called Contest, includes measures to identify those who are vulnerable to becoming involved in extremist activity. This strand, called Prevent, was first developed in 2003. It prioritised community engagement as the most effective way to counteract extremist action. The Prevent strategy was revised in 2011. It now covers most types of extremism, not just Islamic extremism, but it does not directly apply to Northern Ireland-related terrorism, which is the responsibility of the devolved administration in Northern Ireland. Under Prevent, there is a statutory duty on all public sector workers to identify individuals whoe might be at risk of radicalisation. 

The Government’s Counter-Extremism strategy was published in October 2015 and the Counter-Extremism and Safeguarding Bill will follow this year. It will cover all types of extremism as well as targeting non-violent extremism, but will not directly apply to Northern Ireland-related terrorism. The Bill will introduce a new civil order regime to restrict extremist activity (after consultation) and powers to intervene in unregulated education settings.

  • Green steel

    Greenhouse gas (GHG) emissions from the iron and steel industry make up 14% of industrial emissions in the UK. Decarbonisation of the steel industry is needed if the UK is to meet its target of net zero GHG emissions by 2050. This POSTnote outlines current steelmaking processes in the UK, the technologies and measures that can be used to reduce CO2 emissions, and the supporting infrastructure and policies that could enable a ‘green steel’ industry in the UK.

  • Sharing public sector data

    Sharing public sector data can improve public services, facilitate research and innovation, and inform policymaking. However, public sector bodies face challenges when sharing data, both within the public sector and externally. These include cultural and skills barriers, poor data quality, and lack of public trust. Sharing public sector data also raises security and privacy concerns. This POSTnote looks at how public sector data is shared in the UK, discussing the requirements for effective data sharing and the associated benefits, risks, and barriers.
