Stephen Gash is a British anti-Islam activist and a prominent figure in the counter-jihad movement. He is known for co-organizing activities and protests under the banner of Stop Islamisation of Europe (SIOE) in the United Kingdom, an organization aimed at opposing perceived threats of Islamic influence and multiculturalism in Europe. Gash has been a vocal figure in far-right circles, collaborating with international activists such as Anders Gravers, and has participated in demonstrations that often sparked controversy and counter-protests due to their anti-Islam rhetoric. His activism includes organizing events in London and other UK cities, focusing on issues like immigration, Sharia law, and cultural integration. He has been criticized for promoting Islamophobic views and has faced legal challenges related to public order during protests. Despite limited mainstream recognition, Gash remains a key player in niche anti-Islam networks, contributing to the broader European counter-jihad ecosystem through writings, speeches, and organizational efforts.
