The UK government wants a new definition of Islamophobia and has created a working group of politicians, academics and independent experts to provide one. It aims to settle long-running political debates over the term.

The concept of Islamophobia describes anti-Muslim and anti-Islamic prejudices and their impact on Muslim communities. The term became familiar in the UK following publication of the Runnymede Trust report, Islamophobia: A Challenge for Us All, in 1997.

The concept is now used to discuss negative public opinion towards Muslims and Islam, biased media reporting, verbal and physical assaults and online attacks. It is also used when discussing social and economic inequalities, discrimination within various institutional settings and unfair treatment from the police and security services.

Previous definitions have been controversial, failing to unite politicians, academics and British Muslims, and leading to charged debates over free speech.

Some academics have argued that the word "Islamophobia" - which suggests a phobia or fear of Islam - is an inaccurate label for a prejudice which often targets skin colour, ethnicity and culture.

Many Muslim-led organisations accept that the term is imperfect and interchangeable with others such as "anti-Muslim hatred". However, they maintain the term "Islamophobia" is needed to focus attention on a growing problem.

The 1997 Runnymede Trust report defined Islamophobia as an "unfounded hostility towards Islam", "the practical consequences of such hostility in unfair discrimination against Muslim individuals and communities" and "the exclusion of Muslims from mainstream political and social affairs".

The Runnymede Trust revised its definition in a follow-up report published in 2017. The report defines Islamophobia in two ways.

The first is "anti-Muslim racism". A longer, second version amends the United Nation's 1965 definition of "racial discrimination". These revised definitions are important because they re-framed Islamophobia as a product of racist thinking rather than religious prejudices.

Other attempts to define Islamophobia include British academic Chris Allen's 200-word definition. Allen defined it as an ideology like racism that spreads negative views of Muslims and Islam, influencing social attitudes and leading to discrimination and violence. US political scientist Erik Bleich defined it more succinctly as "indiscriminate negative attitudes or emotions directed at Islam or Muslims".

In 2018, the all-party parliamentary group on British Muslims published another definition linking Islamophobia to racism. According to the APPG, "Islamophobia is rooted in racism and is a type of racism that targets expressions of Muslimness or perceived Muslimness." The APPG called for its definition to be legally binding.

The APPG definition was adopted by various organisations including local authorities, UK universities and the Labour party while in opposition. But it was rejected by the then Conservative government and later by the current Labour government, which argued it was seeking "a more integrated and cohesive approach".

This lack of consensus over previous definitions led Angela Rayner, the deputy prime minister, to announce the working group in March 2025. The group's aim is to provide a new definition of "anti-Muslim hatred and Islamophobia" which is "reflective of a wide range of perspectives and priorities for British Muslims".

Former Conservative MP and attorney general Dominic Grieve was appointed to chair the group, evidence of Labour's ambition to build consensus.

Some are concerned that use of the term "Islamophobia", and particularly the APPG definition, stifles legitimate criticism of Islam. Free speech campaigners have argued that it is "blasphemy via the back door".

The centre-right thinktank Policy Exchange published a report claiming that the term is used in bad faith to divert attention away from serious social problems within some Muslim communities - specifically, discussion of the grooming gangs scandal.

These debates bear resemblance to those surrounding the term "antisemitism" and the adoption of a definition proposed by the International Holocaust Memorial Alliance. The term is widely accepted, although critics have argued this specific definition stifles legitimate criticism of the Israeli state.

A new definition of "Islamophobia" must balance the protection of Muslim communities and freedoms of religion, expression and assembly for all Muslims and non-Muslims in the UK. It must be clear enough for everyday use, specific enough for academic and policy research, and capable of generating support across the UK's diverse Muslim population.

A proposed definition by an emerging thought leader on British Islam addresses these challenges. Mamnun Khan is a writer whose work explores the social integration of Muslims in contemporary British society. Khan is associated with Equi, a thinktank which describes its work as "drawing on Muslim insight". Other members of Equi are members of the government's working group.

Khan sets out three tests that a definition must pass, based on Islamic law, moral teachings within Islam and other more universal values. First, a definition must serve the public interest. Second, it must be just and balanced and preserve freedom of expression. Third, it must uphold the dignity of Muslim communities.

For Khan, "Islamophobia, also known as anti-Muslim hatred, is an irrational fear, hostility, or prejudice toward Muslims that leads to discrimination, unequal treatment, exclusion, social and political marginalisation, or violence."

Khan's definition has many good qualities. It brings together stronger elements of previous definitions - for, example, the separation of negative attitudes and outcomes - without being weakened by jargon or strong political ideology. On the other hand, some social scientists may question whether defining something as "irrational" is a matter of preference rather than academic research.

The working group also needs to decide whether Islamophobia and anti-Muslim hatred are closely related or exactly the same. Failure to do so will cause confusion and inconsistency among those wishing to apply the term precisely. Regardless, Khan's example is a strong step in the right direction. A better definition of Islamophobia is needed, and now within reach.
