I have to I'm pretty confused to why people are assuming that KSA is a eutopia for muslims. It is not.
To mummyoverseas, yes it is sad you can't practice as a divorce lawyer, however if you moved to an EU country you may still have the same restriction based on a lack of local qualifications or language skills.
With regards to voting, for women voting is a birth right and as such in other muslim countries they do vote. KSA is doing it's own thing.
Muslim women drive in Pakistan, Malaysia, India in fact in lots of countries. It is just KSA who have decided it is ok for women to be driven around by male drivers rather than drive themselves. Why I don't know.
As for Sharia law in Britain, its no more applied that Jewish law. Jews have rabbinical courts in session, settling personal disputes, divorce and other issues. In the same way muslims have small scale court rooms for men and women to apply for divorces.
And in case you hadn't all guessed I am muslim, I don't wear a burkha, but I do not believe that banning it is the way forward for anyone.
