Waiting for the Tube, I see a poster for an upmarket gym chain. Locations? “City of London. High Street Kensington. Dubai.” What a shame to choose a setting that is so disfigured with bad taste and clueless expats. Still, the City and Dubai branches must be first-rate.  

Soon after, I am in Doha, and again the Euro-Gulf linkage is inescapable. The emir of Qatar is back from a state visit to Britain, where the hosts were angling for a trade deal. Swiss-headquartered Fifa has just given the World Cup hosting rights to Saudi Arabia. Even in skyscraper-free Muscat, where alleys that might have been rationalised elsewhere in the Gulf twist freely behind the corniche, three restaurants in my hotel are outposts of Mayfair brands. 

What a shame the word “Eurabia” is taken. And by such cranks. (It is a far-right term for a supposed plot to Islamise Europe.) Because we are going to need a word for this relationship. The Arabian peninsula has what Europe lacks: space, natural wealth and the resulting budget surpluses to invest in things. For its part, Europe has “soft” assets that Gulf states must acquire, host or emulate to carve out a post-oil role in the world. This isn’t the Gulf’s deepest external connection. Not while 38 per cent of people in the UAE and a quarter in Qatar are Indian. But it might be the most symbiotic, if I understand that word correctly.
