Boris Johnson, the mayor of London, has put his weight behind a new £100 million initiative to fund Arab and Muslim technology entrepreneurs, encouraging them to set up shop in the business-friendly UK.

Exact details of the tech fund have still to be ironed out. But essentially it aims to scale up startups from the Arab world by smoothing the path to expansion in London and letting them take advantage of its expertise in financial and legal services. London does, of course, have one of the fastest-growing hubs for startup technology companies in the world in the form of Tech City.
