The interfering ex-prime minister is distracting the government with his constant threats. Once or twice a year, the approaches to Islamabad, Pakistan’s staid, leafy capital, start to resemble a jumbled cargo port. Piles of shipping containers sprout up at motorway junctions on the outskirts of the city and at strategic crossroads inside it. Lines of riot police stand guard. Residents grumble, knowing traffic will get choked, schools will close and getting to work will take twice as long. The appearance of the barriers, put there by police, signals that the city of 1m is under siege from one of the country’s “long marches”. Do you think that foreigners are behind Pakistan’s falling economy ?
