Bravo! Well done, Britain! It’s “a remarkable national effort,” gloats chief architect George Osborne, “we got there in the end”. Making his spring statement, chancellor Philip Hammond may allow himself a funereal glimmer of an almost smile. The current account deficit has been starved down to its 2% target. So easy! Any dieter determined to lose weight can just lop off their legs and, hey presto, the scales will say they made it. Swallowing tape-worms or emetic poisons will do it too. Easy if you ignore collateral damage, human suffering, irrecoverable losses and economic paralysis. Easy if your aim is ideological state-shrinkage.
