Only a minority of Muslims in the USA support violence in the cause of Islam

That's the claim we hear and similar claims are made about Muslims in the UK. So I was intrigued to read that according to a survey of mosques in the USA:

'51 percent of mosques had texts that either advocated the use of violence in the pursuit of a Shari‘a-based political order or advocated violent jihad as a duty that should be of paramount importance to a Muslim; 30 percent had only texts that were moderately supportive of violence like the Tafsir Ibn Kathir and Fiqh as-Sunna; 19 percent had no violent texts at all.'

Do note that in fact only 4.7% of Muslim worshippers in the USA attended mosques where jihadist materials were not provided because Sharia-compliant mosques promoting jihad were the most heavily attended. Also note that mosques containing violence positive materials were substantially more likely to include materials promoting financial support of terror than mosques that did not contain such texts. A disturbing 98 percent of mosques with severe texts included materials promoting financial support of terror. Those with only moderate rated materials on site were not markedly different, with 97 percent providing such materials.

I wonder what the equivalent figures for UK mosques would be?
