Aldi sold more than 2.5million units of ice cream between Monday and Wednesday across Britain this week as the heatwave grips the nation.

The German supermarket chain said sales of ice cream across its shops rose by 144 per cent week-on-week.

Aldi said sales of barbecue staples have surged during the current heatwave.

The chain said it sold 80 per cent more smash burgers and quarter pounders this week than in the same week a year ago.

Approximately 80,000 hotdogs have been sold in Aldi shops this week alone, the supermarket said.
