LONDON (Reuters) - British workers’ earnings fell in inflation-adjusted terms for the first time in three years during the 12 months to April 2017, according to a major annual survey of households published on Thursday.

The Official For National Statistics said full-time workers’ weekly earnings decreased by 0.4 percent in the year to April, marking the first drop since 2014, due to a rise in inflation after the Brexit vote in June 2016.

In nominal terms, median British full-time employee weekly earnings stood at 550 pounds, up 2.2 percent from 539 pounds in the year to April 2016, the ONS said.
