The cost of living has risen at the fastest rate in 40 years after the Consumer Prices Index inflation went to to 9% in April.
The new figures from the Office for National Statistics (ONS) - a significant rise from the already high figure of 7% in March - come after the increase in fuel prices most customers saw in April, but also include rising food prices and other household costs.
It was the fastest measured rate since records began in 1989, and the ONS estimates it was the highest since 1982. But there was a warning that the rate is likely to climb higher.
