LONDON (AP) — The British economy has not had a worse year since the global financial crisis and Brexit uncertainty is clearly to blame. The government even admits it. Official figures released Monday showed that a lack of clarity over Brexit weighed on businesses throughout 2018 and kept a lid on their investments. For 2018 as a whole, the economy grew by 1.4 percent. The last time it performed so weakly was in 2012, during Europe’s debt crisis. The last time it had a worse year was in 2009, when it contracted by 4.2 percent in the wake of the global financial crisis that brought much of the world’s banking system to its knees.
