Yet Qutb was held up by MAB as a supremely moral being for having “opened his eyes to the malaise of the Western culture and non-Islamic ideologies”. He made a “clear distinction between pure faith and association of partners (shirk)” which bluntly means venerating anything other than God.

At its most extreme, this obsession with purifying the Islamic faith is what also drives Islamic State to kill everything it deems to be impure and is why the mere mention of purity by Islamists sends a Nuremberg-like shudder down my spine, though not, apparently, the spines of many on the Left nor even some conservatives. The commentator Peter Oborne considers the Brotherhood to be “a great political movement — not just in Egypt”.  He says he has “seen no evidence of any kind of Muslim Brotherhood terrorism . . . I’ve looked into it.” But then so have two of Britain’s most senior and expert civil servants with access to Muslim Brother leaders, British embassies around the world, and intelligence from MI5 and MI6 that presumably Oborne did not have. Given violent jihadism’s inheritance from Brotherhood ideology, there is nothing “phobic” about this apprehension. It is rational.

Anas Altikriti and his Cordoba Foundation can talk all the grandiloquent talk they like about “believing” in a “world full of hope” where “opposing ideas are working together, enriching our understanding of each other; strengthening our humanity without seeing its end in a grand clash”.

But until they can reconcile the resounding clash between their enlightened rhetoric and their blind eye to the Brotherhood’s regressive ways, sceptics will continue to question whether the change is real or tactical. Clearly Jenkins and Farr have yet to be convinced. Brotherhood literature here, they say, still casts “Western society” as “inherently hostile to Muslim faith and interests and that Muslims must respond by maintaining their distance and autonomy”.

British society is not inherently “hostile” to Muslims nor ever has been. More than three million Muslims have made their home here and their numbers are growing rapidly. British Muslims are a fact of life. Non-Muslims are crying out for their fellow Muslim citizens to close that distance by articulating a set of values around which a meaningful common life can be built. Until then, the Brotherhood’s British network that claims to speak for “normative” Islam will continue, as the review says, to be regarded as operating “contrary to our national interests and our national security.”
