UK retails sales shoot up by almost 2% last month thanks largely to the panic buying of Petrol before Easter when the driving public was afraid there will be a strike by petrol tankers. Another factor that help increase the increase was the warm weather.

Except from how it was reported by BBC follows:
UK retail sales recorded their biggest monthly rise in more than a year in March, driven by the spell of warm weather and panic buying of petrol.
The Office for National Statistics (ONS) said that UK retail sales volumes rose 1.8% last month.
The ONS said warm weather in March had helped to boost sales of clothing, footwear and gardening products.
The rise follows a decline of 0.8% in February, which was blamed on the squeeze felt by consumers.
Over the past three months, sales volumes were up 0.8% compared with the same period last year.
Concern over a shortage of fuel contributed to the rise in March. Fuel sales jumped 4.9% last month as drivers filled their tanks, fearing a strike by fuel tanker drivers.
