Pay including bonuses rose by an annual 6.4% in the September-to-November period, the biggest increase since records began in 2001 excluding jumps during the COVID-19 period which were distorted by lockdowns and government support measures.

Pay excluding bonuses also rose by 6.4%, the Office for National Statistics said.

Economists polled by Reuters had expected total pay and the ex-bonuses measure to rise by 6.2% and 6.3% respectively.

The ONS said Britain's unemployment rate held at 3.7%, as expected by most of the economists polled by Reuters, close to its lowest level in almost 50 years.

The Bank of England is worried that the acceleration in pay growth will make Britain's high inflation rate - currently running above 10% - harder to bring down.
