My father's from Pakistan and he has been a secularist all his life. In the Pakistani context, there's no messing with religion. There's been a battle for the soul of Pakistan since 1947 and I have grown up without any illusions about the dangers of religious power in the context of a country like Pakistan.

The Muslim Arbitration Tribunal, if you look at its website, it basically deals with commercial disputes, it's not allowed to deal with matters involving children, it's not allowed to deal with criminal matters, it's subject to judicial review, it's subject to the Human Rights Act, it's subject to the Children's Act, and it's completely proper and right that it should be subject to all those things.

People are coupling and decoupling all the time in Great Britain. The fact that Muslims choose to precede it with a certain formula of words, shouldn't bar them from anything. But, no one's saying that polygamy should be institutionalized in this country. That Muslim's uniquely should be allowed to have two or three or four marriages.

Ayatollah Khomeini issued a fatwa to that effect, which was then given effect in the Islamic Republic of Iran, so in the Islamic Republic of Iran, it's flexible enough to allow for sex changes, and it encourages sex changes. But if you want to change your religion in Iran, you've got some serious problems. There are other problems. You're allowed to change sex, but if you want to be a homosexual, theoretically at least, you face the death penalty. Quite how often these penalties are carried out is a moot point, but it's there on the statute books.

I think there's a real danger that Islamophobia can actually be a cover for something far more malign. I don't want to sound like a spokesman for the Muslim Arbitration Tribunal but I am a supporter of autonomy for religious communities and for non-discrimination.

There's crucial distinction that has to be drawn between the Shari'a, which is this hugely expansive vision of cosmic order that I've been describing, and principles of Islamic law, known in Arabic as "Fiqh" - a word that means understanding. If you're a devout Muslim, you don't argue against the Shari'a; the Shari'a is the path that God has laid down. But what you can do, and what people are doing all the time, is arguing over the correct interpretation of the Shari'a, arguing over the Fiqh. That's something that has been going on throughout Islamic history.

There is an issue about the discrimination provisions because the Qur'an does say that women should have half the share of men. Again, in the seventh century perhaps that kind of made sense, but in the twenty-first it very often doesn't. But in the arbitration contract that won't arise. An inheritance dispute might arise after someone dies but the two sides have to come together consensually.
