McDonald's added that it was trialling meal deals at 120 outlets in the South East of England called "Saver Meals" - for example, a cheeseburger, a side order and a drink will cost 拢3.99.

It said the meal bundles were being trialled "to understand if this could be an additional way to offer value to our customers".

Emily Brooks, an apprentice at Francesco Group hair salon and academy in Stafford, said she had noticed food prices were "shockingly high".

"Everyone likes McDonald's," she said. "You could usually get like a meal for under 拢5, some are over 拢6 now. It's not really affordable for young people."

Prices in general have been rising rapidly around the world as food, fuel and energy costs soar.

Russia's war in Ukraine pushed energy prices higher, although crude oil and gas prices have been falling since last summer.

The pace of inflation in the UK was 10.1% in the year to January, down from 10.5% in December, and food price inflation is at a 45-year high.

So an item that cost a pound last January would be more than 10p more expensive this January, across the board.

Firms have responded to rising costs by increasing prices.

Both Coca-Cola and PepsiCo, which dominate the global soft drinks market, pushed through multiple price rises in 2022.

Coca-Cola put up prices by 11% around the world, while Pepsi's prices rose 14%.

On Tuesday Coca-Cola said it would raise the price of its fizzy drinks again this year.

McDonald's too has raised prices before today.

In 2022 its sales grew 10.9% after price rises and as more people came to its outlets.
