The most dangerous form of Brexit Sorrell and the productivity puzzle Aim, at 21, still needs to grow up The boom in British asparagus

Jeremy Warner Anthony Hilton Kate Burgess Editorial

Vote Leave has “pushed exactly the right buttons” in large parts of the country by focusing on immigration, says Jeremy Warner. But in doing so, it has effectively “ruled out the least economically dangerous way of disengaging from the EU”. Were Britain to follow Norway into the European Economic Area, continued access to the single market would be guaranteed. But because it is a founding tenet of the EU that “the single market cannot be disentangled from the principle of free movement”, that would be “incompatible with the introduction of immigration controls”. Make no bones about it, leaving the single market would mean years of uncertainty and severe damage to asset prices – creating just the sort of environment in which “madcap” Leftist ideas could thrive. Indeed, once outside the EU, with no state aid rules to act as a restraint, there’s little to stop Britain becoming like Venezuela: favoured industries could be supported, price controls introduced and the banks torn apart. “Political and economic instability go hand in hand”, and are always “deadly” for prosperity.

School is where she thrives. She is beloved by her teachers, will soon star as young Simba in her year’s performance of The Lion King, and gets straight As. Her school doesn’t offer a maths course challenging enough for her, so she takes algebra online through Johns Hopkins University. Now she’s on her own page, checking the comments beneath a photo of her friend Aisha, which she posted for Aisha’s birthday. “Happy birthday posts are a pretty big deal,” she says. “It really shows who cares enough to put you on their page.”

Rachel, Katherine’s au pair, comes into the room and tells her it’s time to get ready for basketball practice. Katherine nods, scrolling a few more times, her thumb like a high-speed pendulum. She watches Vines – six-second video clips – of basketball games while going upstairs to her room, which is painted cobalt blue. Blue is her favourite colour. She describes most of her favourite things using “we”, meaning they are approved by herself and her friends. Her floor is a tangle of clothes, and her bed is a tangle of cords. One for her phone, one for an ipod, one for her school laptop, and one for the laptop that used to belong to her mother, Alicia.

A blanket with Alicia’s name on it lies across her bed. A photo of her mother on her wedding day sits on her desk. In a frame on her bedside table, handprint art they made together one Mother’s
