Wages in some parts of the UK are worth a third less than a decade ago, according to a report.

Research by the Trades Union Congress (TUC) found that the average worker has lost £11,800 in real earnings in the last 10 years, as reported by The Guardian.

The union organisation said the UK has suffered the worst real wage slump among leading economies.

The biggest losses have been in parts of London, as well as Surrey, North Yorkshire and Anglesey in north Wales.

Employees have suffered average real wage losses from just under £5,000 in the North-East to more than £20,000 in London, said the report.

The TUC said that the government has failed to tackle the cost of living in the UK, leaving millions of families worse off this Christmas than a decade ago. It said that, while pay had recovered in most leading economies, the UK had been left behind.

The government said wages are rising at their fastest rate in a decade, thanks to the national living wage, and there are more people than ever in work.
