What percentage of British Muslims want sharia for family law versus criminal law?

1. Poll headlines: the “40%” figure and its limits

Several outlets and summaries have cited a headline figure near 40–43% of British Muslims as supporting the introduction of some form of Sharia law (Policy Exchange reporting summarized by the National Secular Society and other outlets) ^[1]. That figure reflects aggregated answers about support for “Sharia provisions” or “the introduction of Sharia law” rather than a fine-grained policy preference between family and criminal law, so the 40% headline overstates the precision of the underlying data ^{[1] [2]}.

2. Important nuance: “aspects” and strength of support

Analysis of the same surveys emphasizes nuance: Policy Exchange and other commentators warned that question wording matters and that many respondents did not express active support; only 16% “strongly supported” the introduction of sharia when asked in broader terms ^[2]. Policy Exchange itself stressed that “sharia” is a broad concept and that in day-to-day life many British Muslims do not let it drive their choices—so headline percentages mask varied intensities of support and differing understandings of what “sharia” means ^{[2] [1]}.

3. Family law versus criminal law: what the sources actually say

Available sources do not provide a clear, consistent percentage split showing how many British Muslims want sharia applied to family law only versus criminal law. Most reporting and major studies cited discuss sharia in the context of family matters—marriage, divorce, inheritance—and arbitration bodies like sharia councils and the Muslim Arbitration Tribunal, noting that sharia bodies typically operate within civil or family dispute contexts under UK law rather than enforcing criminal punishments ^{[4] [5] [6]}. The government review and academic pieces describe sharia councils as advisory or arbitration-focused, not criminal courts ^{[5] [6]}.

4. Institutional reality: where sharia operates in Britain

Independent reviews and academic accounts make clear that sharia councils, and arbitration under the Arbitration Act, function in areas such as family, finance and dispute resolution and have no legal authority to impose criminal sanctions; English law takes precedence in equality and human-rights matters ^{[5] [4] [6]}. This institutional fact matters when interpreting poll responses: support for “sharia” may primarily reflect desire for religiously-informed family and personal rules rather than endorsement of criminal law implementation ^{[5] [6]}.

5. Media and political framing widen the gap between data and perception

Right-leaning outlets and polemical sites have amplified fears of a Sharia takeover and at times presented polls as evidence of appetite for nationwide Sharia implementation, including criminal law, but the academic and government sources emphasize that such claims ignore the distinctions between religious arbitration/advice and statutory criminal jurisdiction ^{[7] [6] [5]}. Where polls ask about “desirability” of implementing sharia or “introduction of Sharia law,” interpretation is highly sensitive to question phrasing and to whether respondents imagine family arbitration or corporal criminal penalties ^{[1] [2]}.

6. What’s missing and what to watch for

Available sources do not supply a definitive, methodologically comparable statistic that splits British Muslim support for sharia into family-law only versus criminal-law endorsement; that exact breakdown is not found in current reporting (not found in current reporting). Future clarity requires polling that explicitly asks separate, clearly worded questions (e.g., “Do you support sharia-based family arbitration for consenting adults?” versus “Do you support criminal punishments under sharia enforced by state authorities?”) and that reports intensity of support, regional differences and demographic breakdowns ^{[2] [1]}.

Conclusion — reading the data responsibly

The best-supported claim from the provided reporting is that sizable minorities of British Muslims express support for some form of sharia in broad or family-related contexts (figures around 40–43% appear in summaries), but stronger support is much smaller (16% “strongly support” in one account), and institutional reality confines most sharia practice in the UK to voluntary family/arbitration settings rather than criminal law ^{[1] [2] [5] [6]}. Interpretations that equate poll percentages with a mandate for criminal sharia enforcement are not supported by the available sources.
