What is inflation and why has it been rising?published at 06:29 BST

For example, if a bottle of milk costs £1 but is £1.10 a year later, then annual milk inflation is 10%.
If it had risen to £1.05 instead, then the inflation rate would be lower, at 5%. That would still have been an increase, but a smaller one.
When we say the inflation rate has fallen, that often means prices are still rising, just not as quickly.
The prices of hundreds of everyday items and services, including food and fuel, are tracked by the Office for National Statistics (ONS) to produce the Consumer Prices Index (CPI), with the latest figure published monthly.
The recent rise in inflation has mainly been driven by higher fuel prices, which have dramatically increased since the outbreak of the Iran conflict.
After the US and Israel attacked Iran and its proxies in February, Iran threatened shipping travelling through the Strait of Hormuz, driving up oil transportation costs, including maritime insurance.
