Mannequins stand in a closed clothes shop in Derby, central England, in this September 8, 2009 file picture. Britain's economy is picking up at last but the country has a problem it didn't face after previous recessions and which even now remains hard to detect: the corporate undead. Thousands of companies have subsisted through the downturn thanks largely to accommodating bankers and very low interest rates. As the economy gathers pace, some will recover and flourish, but the weakest of these "zombie firms" will find that competition and a shortage of cash spells the end. If recovery does kill off the weakest, that may mean unemployment gets worse before it gets better, which in turn may be a cue for the Bank of England to keep interest rates lower for longer, casting its forward guidance in a new light.
