The Vatican's needs and Sweden's city on the move

Pascale Harter introduces personal stories, analysis and wit from correspondents around the world. Allan Little analyses some of the currents of dissent and competition swirling around the Vatican City as it prepares for the cardinals' conclave, and explains why Catholics want "a pastoral man" for any new Pope. And far north of the Arctic Circle, above one of the richest seams of iron ore in the world, Steve Vickers visits Kiruna - an entire city that's upping sticks and moving 3km up the road, because all the digging has literally undermined it.
